Aluminum Boride is a black glossy monoclinic crystal with a specific gravity of 2.55 (18°C), insoluble in water, acid and alkali, decomposed in hot nitric acid, and obtained by melting boron trioxide.
Nano-silica powder is added to special refractory materials to form a multi-layer protective layer during oxidation, which has good mechanical properties and high temperature resistance and oxidation resistance.
Nano aluminum nitride (AlN) is prepared by aerosol ablation method, with high purity, small particle size, large specific surface area and high surface activity. The powder treated by surface modification will not undergo hydrolysis reaction and has extre
