High-purity rare earth metals are key raw materials for the research and development of high-tech materials and the basis for obtaining high-performance materials. A small amount or even a very small amount of impurities will have a significant impact on their physical and chemical properties. The ... Read More

Magnesium carbon refractory is a high-quality high-temperature refractory material with excellent refractory and mechanical properties, as well as good corrosion resistance, thermal shock resistance and thermal conductivity. Its preparation process is simple, so it is widely used as lining material ... Read More

The main characteristics of yttrium oxide (Y2O3) transparent ceramics are: ① The crystal structure is cubic, and there is no birefringence inside the crystal, which can be used as a matrix material for preparing transparent ceramics; ② It has a high melting point, indicating that its physical and ...

Cubic zirconia has not been found in nature so far. It is a natural zirconia (monoclinic phase) that undergoes phase change under certain conditions, and changes from tetragonal phase to cubic phase to a high-level structure cubic phase with the most densely packed atoms. With the phase change, its ... Read More

When a lithium battery is about to reach the end of its life, a new molecule can be injected into it to restore its original charging capacity. It can even allow a battery that can only guarantee 6-8 years/1000-1500 charge and discharge cycles to maintain 10,000 charge and discharge cycles, and the ... Read More

At present, there are two main ways to produce hydrogen from solar energy. One is to use solar cells to generate electricity and then electrolyze water, which is highly efficient but the equipment is complex and expensive; the other is to use sunlight to directly decompose water, that is, to use ...

High-temperature alloys refer to a type of metal material with Fe, Co, and Ni as the matrix that can serve for a long time at high temperatures above 600°C. They need to withstand high temperature, high pressure, complex stress, and oxidative corrosion working conditions. They are widely used in ... Read More

The most common application of rare earth fluorides is the raw materials for preparing rare earth metals and alloys by calcium thermal reduction and molten salt electrolysis. For example, in the process of preparing lanthanum, cerium, praseodymium-neodymium and dysprosium-iron alloys by molten salt ... Read More

Ytterbium metal has excellent photoelectric properties, such as low work function, high transmittance, relatively high stability and low surface plasma effect. Most rare earth metals react with hydrogen to form trihydrides and break and pulverize, while ytterbium only forms dihydrides under low ... Read More
