Advanced ceramics have the characteristics of superior strength, hardness, insulation, heat conduction, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, high temperature strength, etc. Therefore, in very harsh environments or engineering application conditions, they exhibit high Stability and excellent mechanical properties have attracted much attention in the material industry, and its application range is also expanding. The global and domestic industries have increasingly strict requirements for high-precision, high-wear, high-reliability mechanical components or electronic components, so the demand for ceramic products has received considerable attention, and its market growth rate is also considerable.
