Definition of inorganic nonmetallic materials

Broadly speaking, it includes ceramics, cement, refractory, enamel, abrasive and new inorganic materials. Inorganic nonmetallic materials are relative to metallic materials. Metal materials are generally the interaction of metal bond atoms; Inorganic nonmetals are generally the result of the interaction between valence bond and ionic bond atoms. The atomic structure of nonmetallic materials is much more complicated than that of metallic materials.

Inorganic nonmetallic materials refer to inorganic materials mainly composed of oxides, carbides, nitrides, borides, chalcogenides (including sulfides, selenides and tellurides) and oxyacids such as silicates, titanates, aluminates and phosphates. Including ceramics, cement, refractories, enamel, abrasives and new inorganic materials.

Classification of inorganic nonmetallic materials; New inorganic nonmetallic materials and traditional inorganic nonmetallic materials

New inorganic nonmetallic materials

There are many kinds of materials, which can be classified as:

I. Classification and characteristics of materials:

1. Materials can be divided into: inorganic nonmetallic materials.

Traditional inorganic nonmetallic materials

Such as cement, glass and ceramics.

New inorganic nonmetallic materials

Such as high-temperature structural ceramics and optical fibers.

metal material

Such as: iron, copper, aluminum, alloys, etc.

polymer material

Such as polyethylene, polyvinyl chloride

Characteristics of new inorganic nonmetallic materials: ① High temperature resistance and high strength.

② It has optical characteristics. ③ It has electrical characteristics.

④ It has biological function.

There are many new inorganic nonmetallic materials, which are listed as follows: piezoelectric materials; Magnetic materials; Conductor ceramics; Laser material, optical fiber; Superhard material (boron nitride); High temperature structural ceramics: bioceramics (artificial bones, artificial blood vessels) and so on.
