Industrial-Grade Anhydrous Sodium Sulfate (Thenardite) – Core Raw Material for Detergent Formulations & Glass Manufacturing
Product Overview
Product Introduction
Sodium silicate (chemical formula: Na2SiO3), commonly known as pyrophorine, glass glue, is a colorless, transparent viscous solid.
Its aqueous solution, commonly known as water glass, is a mineral binder. Its chemical formula is R2O·nSiO2, where R2O is the alkali metal oxide, and n is the ratio of the mole number of silicon dioxide to the alkali metal oxide, which is called the mole number of water glass. Water glass commonly used in construction is an aqueous solution of sodium silicate.
