Learning Chemistry - General Materials


1. Inorganic materials

(1) Metal materials

Pure metals (a few varieties are limited in performance), alloys (cast iron, steel, cupronickel, brass, etc.), alloys often have many special excellent properties, so they are widely used.

(2) Inorganic non-metallic materials

Ceramics, cement, glass (silicate materials) are common traditional inorganic non-metallic materials, optical fiber, artificial diamond, etc. are new inorganic non-metallic materials.

2. Organic polymer materials

(1) Natural organic polymer materials

Natural fibers: cotton, hemp, silk, fur, etc., natural rubber.

(2) Synthesis of organic polymeric materials

Plastic: The main component of plastic is synthetic resin, including thermoplastics (polyethylene, polyvinyl chloride), thermosetting plastics (phenolic plastics), etc.; synthetic fibers: polymeric materials synthesized from low molecular weight materials such as polyester, acrylic, nylon. and others. Synthetic rubber: a class of highly elastic high molecular weight compounds synthesized by low molecular weight compounds, such as styrene butadiene rubber, butadiene rubber, etc.

(3) Composite materials

Fiberglass, carbon fiber, caustic materials and more.
