Flame retardants and halogen sources act on both flame and smoke in a variety of important polymer systems. Health, safety and the environment are important factors in today’s world, and zinc stannate products have no negative impact in these areas. Zinc stannate is an [...]
Zirconium silicide (zrsi), as a zirconium-silicon intermetallic compound, is a kind of high temperature ceramic material with high hardness, high melting point, high conductivity, high thermal conductivity and excellent thermal shock resistance. In view of these superior physical and chemical properties of zirconium-silicon intermetallic [...]
Boride molybdenum compounds with high melting point, high hardness, wear resistance, high temperature resistant, corrosion candle and low coefficient of friction etc., plays a very important role in modern industry, are widely used in metal materials, coating materials, high temperature structural materials, the cathode [...]
Nano Nd_2O_3 powder material was prepared by homogeneous precipitation method. The preparation process, the kinetics of precipitation reaction and thermal decomposition reaction of precursor precipitate were studied. Other lanthanide elements (except promethium) and yttrium oxide were prepared. The main research contents and results are [...]
In tungsten carbide, carbon atoms embedded in the gap of the tungsten metal lattice do not destroy the original metal lattice and form interstitial solid solution, so it is also called interstitial compound. Tungsten carbide can be prepared by heating a mixture of tungsten [...]
As the society attaches great importance to green and environmental protection, new electrochemical energy storage technologies are constantly updated. Lithium-ion batteries, due to their high energy density, high safety, light weight and long life, occupy a large market share in electrochemical energy storage technologies, [...]
Lignin is the only large-scale renewable source of aromatic compounds, and has the advantages of being inedible, widely available and cheap. A wide range of aromatic aldehydes, acids and esters can be obtained by directional catalytic oxygenation of polylignin. Catalysts are the key to [...]
