Difference between sodium silicate and sodium metasilicate
Sodium silicate is made of quartz sand and soda ash, in which the ratio of sand and alkali, said: modulus (m). The solid sodium silicate at high temperature, high pressure can dissolve into the liquid sodium silicate may use. The primary products of sodium silicate are amorphous sodium silicate, such as solid sodium silicate, sodium silicate instant. And subject to certain conditions can be transformed into a crystalline sodium silicate, sodium silicate crystalline dissolved in water under natural conditions, such as the layered sodium silicate, sodium metasilicate and so on.
Sodium Metasilicate: a fingerprint number 1 crystalline sodium silicate. Is the liquid sodium silicate reacts with the liquid caustic soda, after certain conditions into a crystalline silicate, the molecular structure of needle-like arrangement of crystalline structure.
