Sodium silicate
Research on sodium silicate began in the 18th century, and production for industrial use began in the U.S. in the mid-19th century. Production first began in Japan in 1903. Sodium silicate has different physical and chemical properties depending on the molar ratio of its three components: Na2O, SiO2, and H20. Sodium silicate’s properties differ depending on its SiO2/Na2O molar ratio. AGC Si-Tech manufactures it within a molar ratio range of 2.0 to 3.2.
