What are the main types of ceramic raw materials?

Ceramic raw materials are sintered from natural materials such as feldspar, clay and timely, and there are three main types. It is a typical silicate material, and its main components are silicon, aluminum and oxygen, accounting for 90% of the total shell elements. Ordinary ceramics are rich in sources, low in cost and mature in technology. This kind of ceramics can be divided into daily-use ceramics, building ceramics, electrical insulation ceramics, chemical stoneware and so on according to their performance characteristics and uses.

It is made of high-purity synthetic raw materials through precise control technology, and generally has some special properties to meet various needs. According to its main components, there are oxide ceramics, nitride ceramics, carbide ceramics, cermets and so on. Special ceramics have special mechanical, optical, acoustic, electrical, magnetic and thermal properties.

Classification of special materials According to different uses, special ceramic materials can be divided into structural ceramics, tool ceramics and functional ceramics.

Extended data:

The concept of ceramics has developed into a sintered body, which can be obtained by molding and high temperature sintering with the help of three-dimensional bonding materials. This concept also includes glass in the ceramic range.

The theory of studying the structure and properties of ceramics has also been developed: the influence of ceramic materials and internal microstructure (microcrystal surface effect, porous and multiphase distribution) on mechanical properties has been developed. The relationship between the properties of materials (optical, electrical, thermal, magnetic) and molding, as well as the relationship between particle size distribution and bonding interface have also been developed, and ceramics should become the existing form of materials bearing certain properties.
