What is sodium silicate? High strength, strong adhesion and resistance to acid, heat, alkali, and water toxicity make sodium silicate powder a good choice. Na2SiO3 (9H2O), molecular mass 284.20. Colorless orthogonal Bipyramidal Crystals, or white to offwhite powder. It loses six crystalline water molecules during weathering. It dissolves in water. To dilute it, you can use sodium hydroxide. Its melting temperature is 1088. Low toxicity, LD50(oral to rats)1280mg/kg(without crystalline water). Keep in a cool and dry place. It is an acid-oxide; Silicic anihydride has strong chemical properties. It is insoluble with water. It reacts with hydrogen fluoride or hydrofluoric acids to form silicon trifluoride gas. At room temperature, strong alkali solutions react slowly with sio2 in order to produce the silicates. Strong alkali solution will eat glass. Glass bottles containing strong solutions to alkali should not use frosted glasses stoppers. Glass stoppers (glass contains sio2) can be used. Sticky sodium silicate is made to bond the stopper to your bottle. Glass bottles should not be kept in contact with concentrated alkali.

Use of sodium silicate dust
1. Repair cracks in brick wall. Mix water glass with granulated blast furnace powder, sand and sodium fluorosilicate and press it directly into the cracks of the brick wall. This will help to bond and reinforce the brick wall.
2. As an outer surface for fire doors, sodium silicate solution can be used.
3. It can be used in the production of acid-resistant cement or used for the lining a furnace cellar.
4. Prepare silica gel.

Preparation of sodium silicate granules
Method for sodium carbonate: Sodium carbonate (Na2CO3) is mixed with quartz sand and SiO2 (6080 mesh), according to the requirements of the products. The mixture is sent into a horseshoe flame-kiln where it will be fused at 14501500. The high-temperature products molten at high temperatures flow out of the kiln and are either pressed into blocks, or water quenched to form particles using the mold's rollers.

The price of sodium silicate powder
Price will depend on sodium particle size and purity. Purchase volume may also have an effect on the cost of sodium. Large quantities of small amounts will result in a lower price. On the official website of our company, you can see the Price of Sodium.
