Silicon monoxide 99.99%

Dark brown to loess amorphous powder, white cubic crystal; > 1702 ° C, melting point, boiling point of 1702 ° C, the density of 2.13 g/cm3. Mixed acid soluble in dilute hydrofluoric acid and nitric acid. Does not dissolve in water. In air heating generated when white silica powder. A silicon oxide is not so stable, in the air will be oxidized to silica. When a silica slow vapor condensation disproportionation (see disproportionation reaction) and silicon and silicon dioxide. A silicon oxide can be dissolved in hydrofluoric acid and the mixture of nitric acid and release of silicon tetrafluoride.

The nature of the

CAS no. : 10097-28-6 [2]

The preparation of

A silicon oxide can be made of silicon dioxide and elemental silicon at high temperature after rapid cooling system: SiO2 + Si - > the sio 2

use

A solid silica for insulation. As a fine ceramic material has important value.
