Sodium silicate

Sodium silicate is a compound used in cements and textile processing.

Sodium carbonate and silicon dioxide react to form sodium silicate and carbon dioxide.

Sodium silicate commands a 50 to 100 percent price premium over sodium hydroxide, and processors need the equivalent to 0.5 to 1 percent of it to the volume of crude oil as a neutralizing agent, depending on the acidity of the vegetable oil.
