Inorganic non-metallic materials, like metallic materials and organic polymer materials, are an important part of the contemporary complete material system.
Non-metallic material cutting machine points. Oxides, carbides, nitrides, borides, chalcogenides (including sulfides, selenides, and tellurides) of certain elements and oxyacids such as silicates, titanates, aluminates, and phosphates Salt is a general term for the main composition of inorganic materials. Including ceramics, glass, cement, refractory materials, enamel, abrasives and new inorganic materials. Among them, the term ceramics, with the continuous emergence of inorganic materials similar to ceramic technology, the extension of its concept has also continued to expand. **The broad concept of ceramics has almost the same meaning as inorganic non-metallic materials.
Production process classification
Divided into ceramics, glass, cement, refractory materials, enamel, carbon materials, etc. At the same time, new materials have gradually formed some new material categories according to their production technology, use and development status, such as inorganic composite materials, inorganic porous materials, etc. . Some varieties are incorporated into the traditional classification according to habits, for example: ferroelectric, piezoelectric ceramics are incorporated into ceramics; glass-ceramics, optical fibers, etc. are incorporated into glass.
Main ingredient classification
Some can also be classified according to the main components of the material, such as silicate, aluminate, titanate, phosphate, oxide, nitride, carbide, etc.; according to the purpose of the material, there are daily use and construction , Chemical, electronics, aerospace, communications, biology, medical materials, etc.;
According to the nature of the material, there are gelation, fire resistance, heat insulation, wear resistance, electrical conductivity, insulation, corrosion resistance, semiconductor materials, etc.; according to the material state of the material, there are crystals (single crystal, polycrystal, microcrystal), non Crystals and composite materials can also be divided from the appearance of the material, including block, porous, fiber, whisker, film material, etc.
