silica sand foundry source


Sources of Silica Sand: SiO2 is the chemical sign of silica and it is actually the group of minerals which is a mixture of Oxygen and Silicon. This sand is often got in the crystalline state and because of weathering, plankton fossilization takes place and that results in crystallizing SiO2.
