TLDR
In this article, the authors present a process for the manufacture of a sodium silicate solution in a continuous manner from a silicon dioxide-containing material, comprising continuously adding to a reaction zone a stream of said silicon dioxide containing material and a stream containing a sodium hydroxide-sodium carbonate solution, reacting at a temperature and pressure and for a time sufficient to form a sodium-silicate solution.Abstract:
The present invention comprises a process for the manufacture of a sodium silicate solution in a continuous manner from a silicon dioxide-containing material, comprising continuously adding to a reaction zone a stream of said silicon dioxide-containing material and a stream of a sodium hydroxide-sodium carbonate solution, reacting said silicon dioxide-containing material and said sodium hydroxide-sodium carbonate at a temperature and pressure and for a time sufficient to form a sodium silicate solution, and recovering said sodium silicate solution from the reaction zone.read more
