Molecular weight: 44.0838
Dark brown to ocher amorphous powder, white cubic crystals; mp> 1702 ° C, the boiling point of 1880 ° C, density 2.13 g / cc. Soluble in dilute hydrofluoric acid and nitric acid mixture. Insoluble in water. A white silica powder is heated in the air. SiO less stable in the air will be oxidized to silicon dioxide. When a silicon oxide vapor condensation will slow disproportionation (see disproportionation) is made of silicon and silicon dioxide. A silicon oxide can be dissolved in a mixed acid of hydrofluoric acid and nitric acid and the release of silicon tetrafluoride.
