What is ceramics?

The Concept of Ceramics

According to the composition, the materials are divided into metallic materials, inorganic non-metallic materials and organic materials.

The National Academy of Sciences defined ceramics as "inorganic non-technical materials and objects" in 1968.Broadly speaking, ceramic materials refer to all other materials except organic and metallic materials.

Ceramics are materials closely related to human life and production. In the 20th century, high and new technology developed rapidly. Ceramics in the traditional sense are far from satisfying electronics, electrical, thermal engine, energy, space, automation, sensing, laser, communications, computers, etc. With the rapid development of high and new technology, in order to meet the special performance requirements of ceramic materials put forward by new technologies, people have prepared a series of new ceramic materials using the basic principles and processes of traditional ceramics and applied them in modern science and technology. Various functions-mechanical, thermal, acoustic, electrical, magnetic, optical, superconducting and other ceramics are collectively referred to as advanced ceramics. Although it has only experienced half a century of development, in the 21st century, new materials have been discovered and Development, these new materials are widely used in high-tech fields such as information, aerospace, energy, biology, and marine development.
