How to distinguish organic materials from inorganic materials?

Organic materials refer to hydrocarbons, including plastics, fibers, rubber, coatings, adhesives and other fields, which can partially replace metal and nonmetal materials. Inorganic materials refer to mineral raw materials, such as ceramics and cement.

Organic polymer materials Organic polymer materials are also called polymers or polymers. A kind of macromolecules with multiple repeating monomer units, which are composed of one or more molecules or molecular groups (structural units or monomers) bonded by valence bonds.

They can be natural products, such as fiber, protein, natural rubber, etc. Or they can be made by synthetic methods, such as synthetic rubber, synthetic resin, synthetic fiber and other non-biological polymers. Polymers are characterized by many kinds, low density (only 1/7 ~ 1/8 of steel), high specific strength, good electrical insulation and corrosion resistance, and easy processing, which can meet the requirements of various special uses.

Inorganic materials Inorganic materials can be generally divided into two categories: traditional inorganic materials and new inorganic materials. Traditional inorganic materials refer to materials made of silicon dioxide and its silicate compounds, so they are also called silicate materials.

New inorganic materials are made of oxides, nitrides, carbides, borides, sulfides, silicides and various nonmetallic compounds through special advanced processes.
