Sodium orthosilicate is Na4SiO4 (or 2Na2O·SiO2); sodium metasilicate is Na2SiO3 (or Na2O·SiO2); sodium disilicate is Na2Si2O5 (or Na2O·2SiO2); sodium tetrasilicate is Na2Si4O9 (or Na2O·4SiO2). All these compounds are transparent, glassy or crystalline solids that have high melting points (above 800°C;) and are water soluble. They are produced chiefly by fusing sand and sodium carbonate in various proportions.
