Silicon Monoxide Formula

(Silicon Monoxide Formula)

silicon monoxide formula, also known as silica, is a natural mineral found in nature as quartz and is the principal constituent of sand. It is a colorless, odorless, tasteless, non-toxic, inert, non-flammable inorganic compound. Silicon Monoxide powder is used as a raw material for silicon nitride and silicon carbide fine ceramic powder synthesis, and also for preparing optical glass and semiconductor materials. It is not very stable and oxidizes to silicon dioxide in air. It is hardly soluble in water, and soluble in the mixed acid of dilute hydrofluoric acid and nitric acid to release silicon tetrafluoride. It is very insoluble in organic acids and in most other solvents.

Evaporation deposited films of silicon monoxide show a characteristic absorption maximum in the infrared region around 10 microns. This feature allows the state of oxidation to be determined from its wavelength dependence. By changing either the evaporation temperature or the oxygen pressure in the deposition system, films between two extremes of pure silicon monoxide and pure silicon dioxide can be produced.

Silica dust is not toxic, although heavy exposure may cause a reaction similar to metal fume fever in humans. It is also harmless if ingested, but large pieces could obstruct the gastrointestinal tract or lacerate its lining. The dust is a nuisance particulate, but not corrosive. Exposure to freshly formed silica fumes can lead to a respiratory irritation, and silica may be irritated by contact with skin. If skin contact occurs, remove contaminated clothing, wash affected areas with soap and water. If a reaction develops, seek medical attention.
