What are the common silicate materials

The three general types include inorganic glass (silicate glass), glass-ceramic (microcrystalline glass) and ceramics.

Ordinary inorganic non-metallic materials are characterized by high compressive strength, hardness, high temperature resistance and corrosion resistance. In addition, cement in the cementing properties, glass in the optical properties, ceramics in the corrosion resistance, dielectric properties, refractory materials in the heat insulation properties have their excellent characteristics for the metal materials and polymer materials are not as good.

Chemical properties:

Silicate minerals are characterized by their ortho-tetrahedral structure, sometimes these ortho-tetrahedra to chain, double chain, sheet, three-dimensional shelf way to link up. According to the degree of polymerization of orthotetrahedra, silicates are further subdivided into: island silicates, cyclic silicates, and so on.

Silicic acid has a low solubility in water, about 0.002 mol?L-1 at 25°C. Within the solubility range, silicic acid exists as monosilicic acid. Silicic acid polymerization occurs when the concentration in solution is higher than the solubility, and polymerization is an important property of silicic acid, i.e., monosilicic acid polymerizes into oligosilicic acid, which then polymerizes into homopolymeric silicic acid.
