Silicon Monoxide

Silicon monoxide, white cubic crystal or brown powder, is insoluble in water, soluble in a mixture of dilute hydrofluoric acid and nitric acid, reacts with boiling caustic soda solution to form silicate and hydrogen, can be oxidized by halogens, and is easily oxidized in the air to form a protective film of silicon dioxide and become inactive. It has strong reducing properties at high temperatures and can reduce water vapor, carbon dioxide, limestone and other substances; it is often obtained by sublimation of silicon dioxide and elemental silicon powder in a high vacuum above 1400�°C in industry; it is often used to prepare optical glass and semiconductor materials.
Uses Used to make optical glass and semiconductor materials. The overview, physical and chemical properties, preparation methods, and uses of silicon monoxide are edited and compiled by Ding Hong of Chemicalbook (2015-11-16) Chemical properties White cubic or loess-colored amorphous powder. When heat-treated in air, the loess-colored powder turns into white powder. Melting point is greater than 1702�°C. Boiling point is 1880�°C. Relative density is 2.13. Insoluble in water, Chemicalbook is soluble in a mixture of dilute hydrofluoric acid and nitric acid. Uses Silicon monoxide powder is extremely active and can be used as a raw material for the synthesis of fine ceramics, such as silicon nitride and silicon carbide fine ceramic powder raw materials. Uses Used in the preparation of optical glass and semiconductor materials Uses As a raw material for fine ceramics, it has important value. It can also be evaporated in a vacuum and applied to the metal reflector used in optical instruments as a protective film. It can also be used to manufacture semiconductor materials. It is also used in optical glass.
