Among the materials, there is a class called structural materials. These materials have the advantages of withstanding high temperature, not afraid of oxidation, acid and alkali corrosion resistance, high hardness, wear resistance, and low density. ceramics.

Use at high temperatures.

The appearance of certain precision structural ceramics has made up for the weakness of metal materials.

The global and domestic industry's requirements for high precision, high wear resistance, and high reliability mechanical components or electronic components are becoming stricter. Therefore, the demand for ceramic products is very important, and the market growth rate is also considerable.

The characteristics of precision structural ceramics are as follows:

(1) Precision structural ceramics mainly refer to a large class of new ceramic materials that exert their mechanical, thermal, and chemical properties. It can serve in many harsh working environments, and thus has become the key to the realization of many emerging science and technologies.

(2) Precision structural ceramics have the characteristics of superior strength, hardness, insulation, thermal conductivity, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, high temperature strength, etc. Therefore, under very severe environmental or engineering application conditions The high stability and excellent mechanical properties exhibited have attracted much attention in the materials industry, and its range of use has gradually expanded.

(3) Precision structural ceramics are advanced ceramics with excellent mechanical, thermal, and chemical properties such as high temperature resistance, erosion resistance, corrosion resistance, high hardness, high strength, and low creep rate. They are often used in various structural components. Precision structural ceramics are divided into two types: oxide ceramics and non-oxide ceramics.
Oxide ceramics are represented by alumina ceramics and zirconia ceramics, and non-oxide ceramics are represented by silicon nitride ceramics and silicon carbide ceramics.
