What is silicon monoxide powder?

Silicon monoxide is an inorganic compound, chemical formula SiO, at room temperature and pressure for black-brown to yellow color amorphous powder, melting point 1702°C, boiling point 1880°C, density 2.13g/ cm ³, difficult to dissolve in water, can dissolve in dilute hydrofluoric acid and nitric acid mixed acid and release silicon tetrafluoride, when heated in the air to produce white silicon dioxide powder. Silicon monoxide is less stable and oxidizes to silicon dioxide in the air. As the vapor of silicon monoxide slowly condenses it disproportionates (see disproportionation reaction) to form silicon and silicon dioxide.

Silicon monoxide powder preparation and application
Silicon monoxide can be made by silica and elemental silicon at high temperature after rapid cooling: SiO2 + Si → 2SiO.
The silica powder with SiO2 content of 99.5% is mixed with coal pitch powder with a C/SiO2 mixing mole ratio of 2.0. The mixture is subjected to reduced pressure heating at 1600℃ and 1.013 kPa.Silicon monoxide powder below 0.1 μm was prepared.SiO2 + C - > the SiO + CO.
Because of its high activity, silica micro powder can be used as raw material for the synthesis of fine ceramics, such as silicon nitride and silicon carbide fine ceramic powder. Used for optical glass and semiconductor materials.
Vaporized in a vacuum, it is coated on metal reflective surfaces used in optical instruments as a protective film. Preparation of semiconductor materials.
Silicon monoxide powder properties and stability
Silicon monoxide is less stable, oxidizing to silicon dioxide in the air, and is stable only above 1200℃.
Avoid light, open fire, and high heat. Insoluble in water, soluble in dilute hydrofluoric acid, and nitric acid mixed acid.Good insulators of heat and electricity.Oxidation in the air to form silicon dioxide film and passivation. It burns in oxygen, reacts with water to form hydrogen. Hydrogen is formed in a warm solution of alkaline water and dissolved into silicates.
