Middle School Chemistry Classification of Various Materials

Classification of materials in junior high school chemistry Inorganic metallic materials Pure metals:

Iron, copper, aluminum and other pig iron, steel, bronze, alloys:

Brass, stainless steel materials Inorganic non-metallic materials:

Organic polymers natural organic polymer materials synthetic organic polymer materials ceramics, ordinary glass and other natural fibers: cotton, hemp, silk, wool natural rubber synthetic fibers synthetic rubber plastic composites:

Reinforced concrete, asbestos mesh, glass fiber reinforced plastic and so on.

Natural organic polymer materials organic polymer materials: organic polymer compounds made of materials is organic polymer materials. Organic polymer materials are divided into: (1) natural organic polymer materials: for example: cotton, wool, natural rubber. (2) synthetic organic polymer materials: for example: plastics, synthetic rubber, synthetic fibers, etc., referred to as synthetic materials.
