Crystal boron powder is an inorganic substance composed of boron, its molecular formula is B2O3. The physical properties of crystalline boron powder mainly include its white powdery appearance, high density and low electrical conductivity. This material has good stability to heat and chemicals, and its high density makes it widely used in glass and ceramic manufacturing. Chemically, crystalline boron powder shows a strong reaction to acids, especially with strong bases such as sodium hydroxide. It can form various boric acids, which is its importance in chemistry and materials science. The main use of crystalline boron powder is as an additive to glass and ceramics to increase their hardness and strength. It can also be used in the production of borax and other borates, which have applications in glass, ceramics, detergents and cosmetics.
