What are the traditional inorganic nonmetallic materials?

Traditional inorganic nonmetallic materials are:

1. Cement and other cementing materials: Portland cement, aluminate cement, lime, gypsum, etc.

2. Ceramics: clay, feldspar, talc and ashes ceramics.

3. Refractory materials: silica, aluminosilicate, high alumina, magnesium oxide, chrome magnesia, etc. Glass silicate.

4. Enamel: steel plate, cast iron, aluminum and copper tires, etc.

5. Cast stone: diabase, basalt, cast stone, etc.

6. Abrasives: silica, alumina, silicon carbide, etc.

Composition structure

In terms of crystal structure, the crystal structure of inorganic nonmetals is far more complicated than that of metals, and there are no free electrons. It has stronger ionic bonds and mixed bonds than metal bonds and pure valence bonds.

The unique high bond energy and strength of this chemical bond endow this kind of material with basic properties such as high melting point, high hardness, corrosion resistance, wear resistance, high strength and good oxidation resistance, as well as wide conductivity, heat insulation, light transmittance and good ferroelectricity, ferromagnetism and piezoelectricity.
