Silica (Sio2) - an overview | ScienceDirect Topics

Silica, SiO 2 occurs in nature as a dense rock quartzite and as silica sand. Sand is the preferred raw material for ceramics as it does not need the energy-consuming crushing process. Quartzites however dissolve more rapidly than sand in the molten phase as indicated by the transformation rate to cristobalite during heating ( Schuller, 1997 ).
