Silicon monoxide CAS10097-28-6 , a white cubic crystal or brown powder, insoluble in water and soluble in a mixture of dilute hydrofluoric acid and nitric acid. It reacts with a boiling caustic solution to form silicates and hydrogen gas, which can be oxidized by halogens. It is easily oxidized on the surface in air to form a protective film of silica and becomes inactive. It has strong reducibility at high temperatures and can reduce substances such as water vapor, carbon dioxide, limestone, etc; In industry, it is often obtained by sublimation of silicon dioxide and elemental silicon powder after reaction at high vacuum above 1400 ℃; Commonly used in the preparation of optical glass and semiconductor materials.
