SAFETY DATA SHEET Crystalline Silica in the form of Quartz

Crystalline silica exists in several forms, the most common of which are quartz (i.e. this product), trydimite and cristobalite, with quartz being the most common form found in nature. If quartz is heated to more than 870˚C, it can change form to trydimite and if quartz is heated to more than 1450˚C, it can change form to cristobalite.
