Silica And Silicates

Silica (SiO2) is silicon dioxide that contains silicon and oxygen, while silicate is a class of minerals that is formed with the mixture of silicon, oxygen and reactive metals. Both are different, and are used in building material, glass, ceramics, pottery and other industries. Our company, Avanschem supplies both, silica and silicates. Customers can come to us to buy Precipitated Silica in white powder form. A solution with silicate salts is used to form it by precipitation. The silicates available are sodium aluminium silicate, hydrated calcium silicate and aluminium silicate. These chemical compounds have their own applications.  Sodium aluminium silicate is mainly used as food additives, while hydrated calcium silicate is used in cement based material, and aluminium silicate is used in paper, rubber and paint industries.
