Rare earth nitrides have a very high melting point (for example, the melting point of yttrium nitride reaches 2570℃) and are very stable at high temperatures. Yttrium nitride powder can be used in tantalum powder metallurgy to improve the processing properties of tantalum powder. It is also expected ... Read More

Due to the restrictions imposed by health and environmental regulations on the use of traditional heavy metal color pigments, Rhodia of France has successfully developed a new type of non-toxic color inorganic pigment based on rare earth element compounds. The company first launched a rare earth ... Read More

Natural rubber (NR) has a complex composition. In addition to the main component cis-1,4-polyisoprene, it also contains a small amount of non-rubber substances such as protein, fatty acids and ash. NR has excellent properties, not only good elasticity and crack growth resistance, but also low heat ... Read More

The main uses of europium oxide are as an activator for red phosphors in color TV sets, phosphors for high-pressure mercury lamps, stimulated emission phosphors for new X-ray medical diagnostic systems, etc. The rise of white light LEDs has driven the development of phosphors in systems such as ...

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 ...
