General characteristics of inorganic nonmetallic materials

It is a general term for all materials except organic polymer materials and metal materials.

Inorganic nonmetallic materials are materials composed of oxides, carbides, nitrides, halogen compounds, borides, silicates, aluminates, phosphates, borates and other substances.

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.
