Liquid and solid forms of sodium silicate. The most versatile industrial silicate serving 20+ industries worldwide.
Understanding Sodium Silicate (Water Glass) and its industrial applications
Sodium Silicate, commonly known as Water Glass, is one of the most versatile industrial chemicals available. With the general formula Na2O · nSiO2, it is produced by fusing high-purity silica sand and soda ash at high temperatures. The modulus (SiO2/Na2O ratio) determines its properties and application suitability.
Zhongzhi Chemical supplies sodium silicate in both liquid solution (various concentrations and moduli) and solid glass/lump forms. Our production lines deliver consistent quality for customers across detergents, construction materials, paper making, textiles, foundry, ceramics, water treatment, and many other industrial sectors.
As a versatile and cost-effective industrial chemical, sodium silicate serves as an adhesive, binder, deflocculant, detergent builder, and surface hardener. Its unique combination of alkalinity, solubility, and reactivity makes it indispensable across more than 20 industries.
