    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). Quartz is added to ceramic bodies as filler.
