Sodium silicate commonly known as paohuajian, is a colorless, transparent viscous solid. Sodium silicate is fused with quartz sand and sodium carbonate; soluble in water is alkaline, its transparent slurry solution called water glass. For analytical reagent, fire retardant, adhesive. Is a kind of mineral binder.

Light blue cullets , liquid
3), The usage of sodium silicate
1, The solid sodium silicate main raw material used primarily as silica, silica gel, zeolite, molecular sieve, white carbon black, adsorbents and other production purposes.
2, After making the solid into the liquid , the liquid sodium silicate is mainly used for paper, soap, construction, precision casting, anti-corrosion materials, textile industry, mineral flotation.
