Sodium Silicate Process with reaction in liquid phase:
Caustic soda, quartz sand and water are mixed in a mixing tank, and then the mixture is fed into a reactor, where steam is introduced.
The reactant is liquid water glass with its module lower than 3.
The reaction is as following:
nSiO2+2NaOH → Na2O·nSiO2+H2O
2. Sodium Silicate Process with reaction in solid phase (thermal process)
The feed materials in this process are sodium carbonate and quartz sand, or sodium sulfate and quartz sand. The feed materials are heated in a reflection furnace. The reaction is as following:
Na2CO3 +XSiO2 → (Na2O)•(SiO2)X + CO2
4Na2SO4 +2C +4SiO2 → 4Na2SiO3 +4SO2 +2CO2
Application of Sodium Silicate :
The special nature of sodium silicate makes it the basic raw material for silicon compounds. Whether it is used directly as a substrate or carrier, or as an intermediate for further processing, it is widely used.
Sodium silicate is used in the chemical, light industry, metallurgical and mechanical foundry industries, textile industry, construction and building materials industries, and agriculture.
