When in a solid state, sodium silicate appears as white, crystalline powders. However, its most commonly encountered form is as a clear, thick liquid solution. Manufacture of Sodium Silicate. Traditionally, sodium silicate is manufactured using a reaction between silica sand and sodium carbonate, often facilitated by a high temperature melt.
First is "gelation" in which sodium silicate and water react with CO 2 gas to form a mixture of sodium carbonate and silica gel along with water. The CO 2 and the water in the binder form carbonic acid. Sodium silicate is alkaline. When the carbonic acid is formed, the pH of the silicate falls, reducing the amount of soda and increasing the silica.
Sodium silicate is also known as water glass; a salty composite has significant attraction to water. It is generated by liquefying silica sand and soda ash at a temperature of 1200–1400 °C . Sodium silicate has been normally available in both powder and liquid form .
Silica Sand (SiO2) is relatively pure form of common sand with lower Silica percentage compared to Quartz rock plus some impurities. Iron Oxide is usually the most objectionable. It is used in abundance in Glass, Refractories, Cement and Sodium Silicate industries.
Sodium Silicate is a compound mixture of sodium oxide i.e. Na2o with silica sand i.e. Sio2 with water. Sodium silicate is also called water glass. ...

Colloidal silica is formed by titrating active silicic acid into a heated KOH with seed solution. The colloidal silica formation mechanisms are investigated by sampling the heated solution during titration. In the initial stage, the added seeds were dissolved. This might due to the dilution of seed concentration, the addition of potassium hydroxide …
