Special Shaped Wear-Resistant Ceramic Pieces Porcelain Eyes
Special-shaped ceramics have excellent strength, hardness, insulation, thermal conductivity, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, high temperature strength and other characteristics. Therefore, it shows high stability under very harsh environment or engineering application conditions. The mechanical properties have aroused widespread concern in the material industry, and its scope of use is also expanding. Global and domestic industries are becoming more and more strict with high precision, high wear resistance, high reliability mechanical parts or electronic parts. Therefore, the demand for ceramic products has received great attention, and its market growth rate is also considerable.

Ceramic shaped pieces are hailed as one of the materials for the development of the 21st century.
Alumina ceramics have the characteristics of high hardness, high temperature resistance, acid and alkali corrosion resistance, wear resistance, ultra-high frequency insulation, etc.
The application prospect of ceramics is broad, and it is widely used in various industries such as aerospace, aviation, military industry, nuclear energy, machinery, textile, chemical industry, electronics, food, medical treatment and so on. Our advanced ceramic products are made of zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products have two parts: one part is ceramic rods, tubes, sleeves, plates, blocks, bars and other ceramic materials, and the other part is industrial precision ceramic parts and civilian products.
According to customer needs, various non-standard shaped ceramics, special ceramic accessories, porcelain tubes, porcelain rods and electrical ceramics can be customized, and sample processing can be performed.
