Ceramics

Ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering.
It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance.
It can be used as structural material, tool material, and because ceramics also have some special properties, they can also be used as functional materials.
classification
Common materials
It is sintered from natural raw materials such as feldspar, clay and quartz. It is a typical silicate material. The main constituent elements are silicon, aluminum and oxygen. These three elements account for 90% of the total crustal elements. Common ceramics have rich sources, low cost and mature technology. This kind of ceramics can be divided into daily ceramics, architectural ceramics, electrical insulating ceramics, chemical ceramics, etc. according to their performance Characteristics and uses.
1.Special materials
It is made of high-purity synthetic raw materials and formed and sintered by precision control process. It generally has some special properties to meet various needs. According to its main components, there are oxide ceramics, nitride ceramics, carbide ceramics, cermets, etc; Special ceramics have special mechanical, optical, acoustic, electrical, magnetic, thermal and other properties.
2.Classification of special materials
According to different uses, special ceramic materials can be divided into structural ceramics, tool ceramics and functional ceramics.
