Water → Sodium orthosilicate

Participants

Reaction Steps

As a starting material for producing a silica sol, there was used a water glass having an SiO2 content of 28.5% by weight and an Na2O content of 9.5% by weight. 10.0 kg of the water glass was dissolved in 30.0 kg of water, to thereby obtain a diluted aqueous solution of sodium silicate having a sodium silicate content of 7.13% by weight in terms of SiO2.
