nature : Na2O nSiO2 also known as sodium silicate. Gu said the sodium silicate. Intron different from the proportion of sodium oxide and silica formed. Silica Oxide and the molar ratio of sodium said modulus. Modulus is more than three "neutral" water glass, less than three is "basic" water glass. A liquid, solid and a variety of products such as powder. Most of the liquid, transparent colorless or light gray with the thick, physical nature with modulus vary. For the SiO2/Al2O3 oil FCC catalyst, soap filler, the adhesive corrugated metal preservatives, water softener, detergent additives, raw materials for ceramics and refractories, textile bleaching, dyeing and pulp, mining beneficiation, waterproof, plugging, wood fire, food preservation and the adhesive system, silica, silica sol, zeolite, white charcoal. Production methods are dry and two wet. Dry Soda is (or sodium plus coal) and quartz sand under high temperature melting white, and then cooling, smash, dissolved concentration derived. Wet is liquid caustic soda and quartz sand generated from heating. Wet difficult system high modulus product, but it is simple and easy to get raw materials and low-cost advantages.
