What is the definition of inorganic nonmetallic materials? Glass, right?

Glass is a traditional inorganic nonmetallic material.

The so-called materials generally refer to substances that human beings can use to make useful articles. Materials are the material basis for human survival and development, and have always been an important milestone in human progress.

For example, the Stone Age, Bronze Age and Iron Age in history are all marked by materials. The successful development of a new material can cause new changes in human culture and life. Inventions of stone tools, ceramics, iron, copper, glass, cement and organic polymers (such as plastics). ) and single crystal materials provide an important material basis for human progress.

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.
