Silica is one of the most abundant oxide materials in the earths crust which because of its chemical inertness and considerable hardness is quite resistant to weathering. Silica is a group IV metal oxide, it has good properties like abrasion resistance, electrical insulation and high thermal stability. It is insoluble in almost all acids.Silica sand is the major component of glass, foundry molds, and abrasives. It is also used in ceramics, on golf courses, and as a filter medium.
