Authors: P. R. Carey, Greg Sturtz Sand Binder Systems
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.
