Aluminum and aluminum alloys have a series of advantages such as light weight, high strength, corrosion resistance and recyclability. They are widely used in building materials, decoration, aerospace, automation industry, etc. A large number of aluminum products can be recycled after reaching the ... Read More

The atomic radius of rare earth is generally between 0.1821 and 0.2042 nm, while the atomic radius of iron is 0.1241 nm. The difference between the two is large, so the solid solubility of rare earth in steel is generally very low. A large number of studies have shown that the addition of trace rare ... Read More

Molten salt electrolysis is the main method for large-scale preparation of rare earth metals and their alloys, and it has the lowest cost, highest efficiency, and mature industrial application. Molten salt electrolyte is the main carrier in the electrolysis process, and the physical and chemical ... Read More

Gas turbines and aircraft engines are important power equipment. In order to improve output power and operating efficiency, gas turbines have been developing towards increasing turbine inlet temperature in recent years. At present, the turbine inlet temperature of ground-based gas turbines is above ... Read More

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
