Properties: Sodium silicate is a white solid that is soluble in water, producing an alkaline solution. Melting point 1088° C, Sodium silicate is stable in neutral and alkaline solutions. In acidic solutions, the silicate ion reacts with hydrogen ions to form silicic acid, which when heated and roasted forms silica gel, a hard, glassy substance.
Product Description
Appearance: Liquid, solid and powder
Color: White
Physical character: Has various products such as liquid, solid and powder. The liquid, colourless lucency and the thick thing bringing light gray, physical property be different with the modulus. Liquid sodium silicate, is one kind of colourless, has just a little, transparent or semi-transparent thick shape liquid. Solid sodium silicate is colourless, has just a little, the transparent or semi-transparent glass form of block. Dissolve in water assume alkalescence. Be decompounded meeting acid (carbon dioxide in air also canarouse decomposition) and be separate out the silicic acid gelatine deposition. The anhydrous thing is amorphous, caeruleous or yellow green, is vitrescence. The relative density follow the modulus lessening but enhance. There be no fixed melting point.
