Sand: Silica Sand: Definition and Uses
One of the main factors is the level of purity. High-purity silica sand, which has a silica content of over 99%, is more expensive than lower-purity sand. Another factor is the grain size. Fine-grained silica sand is typically more expensive than coarse-grained sand due to the additional processing required to achieve the smaller grain size.

SAFETY DATA SHEET
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.
