Chromium carbide is a high melting point inorganic material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment (1000~1100℃).

Titanium Carbide is stable to air at temperatures below 800°C, and is slowly oxidized at 800°C, but powdered TiC can be burned in O2 at 600°C to generate TiO2 and CO2.

Spherical quartz powder is made of natural quartz stone after purification and ultra-fine grinding, and through a certain high temperature field, its phase, crystal form and shape change instantaneously, from solid state to molten state and then to solid
