Sodium silicate has a very wide range of USES, almost throughout the various sectors of the national economy.

In chemical systems are used to produce silica gel, white carbon black, zeolite molecular sieves, sodium metasilicate, silica sol, the layer of silicon and instant powdered paohuajian, potassium sodium silicate and other silicate products, is a basic raw material of silicon compounds. Is detergent washing powder, soap, etc. In the light industry in the indispensable raw materials, is also a water softener, settling agent; In the textile industry for assisted dyeing, bleaching and sizing; In the machinery industry are widely used in casting, grinding wheel manufacturing and metal preservatives, etc.; In the construction industry used in the manufacture of alumina cement, acid-resistant cement waterproof oil, soil stabilizer, refractory materials, etc.; Can be made of silicon fertilizer in agriculture; Another paohuajian as adhesive, widely used in cardboard boxes (corrugated) of the adhesive. Phosphorus detergent pollution of water resources, is now fully replace the place of phosphorus to help lotion needs to meet at the same time help lotion 3 big functions: demineralized water, the necessary basic and good ability to resist to settlement.

Of the latest generation without phosphorus help lotion, only of layered crystal sodium disilicate reach three requirements above, and can have a quick exchange of calcium and magnesium, soluble in water, and bleach has good intermiscibility, and easy to enrichment characteristics, so is the prospect of the best without phosphorus detergent, but there is no mass production in China. Domestic demand is now rely on imported from abroad, import price 10000 yuan/ton. It is estimated that China has no phosphorus help lotion every domestic demand will reach 50 ~ 800000 tons. Layered crystal sodium disilicate has four different crystal structure (a - b -, g -, d -), with no water type d d - Na2Si2O5 for the ideal.
