Electrochromic Tungsten Oxide Smart Glass Research or Boosting Fuel Cells Evolution

Recent research has found tungsten carbide rods that electrochromic tungsten oxide smart glass plate research or providing new ideas for fuel cells research and development. Smart glass is an energy-efficiency product found in newer windows of cars, buildings, and airplanes, slowly changes between transparent and tinted at the flip of a switch.

However, smart glass usually takes a few minutes to reach a dull state, and repeated cycles between light and dark for a long time will also reduce the quality of the coloring. Chemists have devised a potentially major improvement to both the speed and durability of smart glass by providing a better understanding of how the glass works at the nanoscale.

According to foreign media reports, Colorado State University chemists, by better understanding the working principle of smart tungsten carbide burrs blank glass at the nanometer scale, proposed a nano-scale smart glass design method or will improve the color-changing speed of smart glass and durability. This method may also be used to guide the application of fuel cells.

The school's graduate student Colby Evans and assistant professor of chemistry Justin Sambur studied the "electrochromic" smart glass, which works by using a voltage to drive lithium ions into and out of thin, clear films of a material called tungsten oxide. “You can think of it as a battery you can see through,” said Evans. Typical tungsten-oxide smart glass panels take seven to 12 minutes to transition between clear and tinted.

The researchers focused on electrochromic tungsten oxide nanoparticles, which are 100 times smaller than a human hair. Experiments have shown that the coloration speed of a single nanoparticle is four times faster than that of a film composed of the same particle. This is because the interface between the nanoparticles in the film captures lithium ions slows down the coloring behavior. The performance of the material will also decrease over time.

To prove their point, the researchers used a bright field transmission microscope to observe how the tungsten oxide nanoparticles absorb and scatter light. When making "smart glass" samples, they constantly change the amount of nanoparticle material in the sample. As the nanoparticles increase, they observe the mutual contact between them and the change in coloring behavior. They then used scanning electron microscopy to obtain higher-resolution Tungsten Carbide Rods images of the length, width, and spacing of the nanoparticles, so they could tell, for example, how many particles were clustered together, and how many were spread apart.

Based on the experimental results, the researchers suggest that if nanoparticle-based materials are fabricated and the particles are kept at an optimal spacing to avoid trapping of ions, it is possible to improve the performance of electrochromic tungsten oxide smart glass. Their imaging technique offers a new method for correlating nanoparticle structure and electrochromic properties, the improvement of smart window performance is just one application that could result. Their approach could also guide applied research in batteries, fuel cells, capacitors, and sensors.

China DyFe Price

Rare earth market quotation in China: the DyFe price declines slightly while praseodymium neodymium metal price rises early in this week. As the prices of mainstream products continue to rise, downstream users' fear of high prices has also increased, resulting in a weakening of the bullish confidence of holders, a slight increase in the awareness of active shipments, and rational quotations.

In the light rare earth market, the fundamentals are good. Affected by the insufficient supply of some products and low activity of downstream inquiries, many suppliers still have a strong psychology of reluctance to sell; in the medium and heavy rare earth market, the prices of a few products have fallen. In the early stage, supported by various Tungsten Weights favorable factors such as the small inflow of overseas raw materials and the limited release of domestic production capacity, traders' quotations have been raised all the way. However, due to the insufficient consumption capacity of rare earth separation plants, the spot prices have recently adjusted slightly.

First Global Rare Earth Industry Association Was Established

The Global Rare Earth Industry Association (REIA) was established at the European Institute of Innovation and Technology (EIT) raw materials organization headquarters in Brussels, Belgium. REIA is a Brussels-based international rare earth association that provides an interoperable platform for rare earth-related companies to mitigate business risks in the rare earth value chain and provides members with assistance in the environment, technology and market dynamics related to rare earth.

REIA said that the establishment of the association coincided with the escalation of the global trade war. Besides, the rapid development of new energy technologies has led to explosive growth in demand for rare earth, and the supply is under pressure.

The association was initiated and founded by 12 members, respectively are Grundfos, Fujian Changting Golden Dragon Rare-Earth Co., Ltd., BRUGGER, B&C Speakers, Jinli Permanent Magnet Europe, Japan Material Trading Corporation, Japan New Materials Society, Talaxis, UK Mkango, Rocklink Rare Metals Recycling, Institute of Urban Environment of Chinese Academy of tungsten carbide plates Sciences and Carester of France.

At the first membership meeting of REIA, representatives of each sponsoring company were appointed as members of the association's board of directors. Among them, Dr. Badrinath Veluri of Grundfos was elected as the president of the first association, Myriam El Kara of Talsis and Shimizu Kotaro of Japan New Materials Society were elected as the vice president, and Shimizu Kotaro of Jinli Permanent Magnet Europe was elected as the chief financial officer. All of the above personnel were appointed for a term of three years. At the same time, the association also invited the expert group to set up an advisory committee.

At the meeting, Dr. Nabir Mancheri emphasized that “the primary mission of the Global Rare Earth Industry Association tungsten carbide burrs is to ensure market transparency and sustainability in the rare earth industry and to provide and build an interoperable platform for the global rare earth industry. Our members will work together to adopt a coherent approach to raw material policies and related issues, and look forward to more members joining us."

Fujian Changting Golden Dragon Rare-Earth Co., Ltd. of China is a leading enterprise in the rare earth industry in Fujian Province, which is a wholly-owned subsidiary of Xiamen Tungsten Co., Ltd., and it mainly engaged in R&D and application of separation, deep processing, and functional materials. The company has a relatively complete industrial chain from mining, separation to rare earth metal, and deep processing (phosphor, magnetic materials).

Another Chinese research institute, the Institute of Urban Environment of the Chinese Academy of Sciences, is a legal entity affiliated to the Chinese Academy of Sciences. It is currently the only national research institution specializing in comprehensive research on the urban environment, which carries out theoretical and technological research and development, system integration and engineering demonstration in the fields of a circular economy, urban planning, and environmental policy.

The Global Rare Earth Industry Association will contribute to capacity building for industry practitioners via enhanced networking among stake holders worldwide, and a better understanding of rare earth value chain, towards a conjoined and coherent approach towards raw materials policies and investments.

Tungsten West Plans to Restart Hemerdon Mine for 2021

The Hemerdon tin-tungsten mine in Plymouth, UK is known as one of the largest tungsten deposits in the Western world. The mine faced a challenging past with its previous owner, Australian specialty metals miner Wolf Minerals, reopening in 2015 but being mothballed in 2018 after failing to reach expected recovery rates. Tungsten West acquired the mine for less than 3 million pounds (3.7 million US dollars) in November 2019, and is further studying ore bodies and processing technology to create an economically viable supply chain. Argus recently conducted a telephone interview with Max Denning, CEO of the company.

Hemerdon is currently receiving care and maintenance. A few employees keep their distance and no employees are infected with the novel coronavirus. They have completed initial test work and are currently conducting a feasibility study, which is expected to be completed this year or the first quarter of 2021. The feasibility study has completed further financing and the reconstruction time is 6 months.

The historical data of the mine was not fit for purpose. The old processing plant did not account for certain nuances of the ore, the most obvious is the fragility of the ore, so there was not enough recovery rate in its three-year operation. In addition, the plant's lack of stability and capacity expansion led to excessive downtime. After six months of technical investigation and detailed study of the characteristics of the ore, we found that the mineral is tungsten iron ore. Therefore, the company has designed a new processing route.

First, the company will implement x-ray transmission tungsten carbide burrs blank ore sorting, a pre-concentration technique that scans the density of each rock and removes barren materials. The ore body is massive and contains coarse iron sphalerite crystals, which makes it the best choice for ore sorting. The additional ore sorting step will significantly reduce downstream processing costs, and feed into the concentrator plant, leading to a much cleaner and higher-grade ore.

They also plan to introduce wet high-strength magnetic separation next to the existing fine-grain gravity circuit because iron sphalerite is quasi-magnetic. This means it concentrates via magnetic separation. Upgrade works on the dense media separator [DMS] circuit was completed during Wolf's era and with a few further required modifications, the DMS will operate well as the main method of concentration for the Tungsten Carbide Rods coarse circuit.

Wolfe Minerals has invested more than 200 million pounds in the Hemerdon mine. Part of the ongoing improvement work has already been spent. Overall, the restart costs including rebuild, modifications, and working capital are expected to be between 30 million and 40 million pounds.

Shortly after the Hemerdon project entered bankruptcy management in August 2019, the APT inventory (about one-third of APT consumption) in the now-defunct Fanya Metal Exchange had an impact on the market, causing prices to fall sharply.

Tungsten concentrate buyers need to secure supply. Outside of China, tungsten concentrate is a rare commodity. China also has a ban on the export of concentrates. and as there are few producers of tungsten concentrates in the rest of the world, there is a gap to fill. Tungsten West is in talks with a multitude of potential buyers on offtake agreements. With the Hemerdon mine, it would be one of the biggest producers of tungsten concentrate outside China at a time when there may be a certain level of increased scrutiny over supply chains.
