We are engaged in manufacturing and supplying Ceramic Seals. Ceramic Seals exhibits high hardness, good abrasion resistance, high strength, and stability. These products are developed incorporating sophisticated technology and are made available to patrons at market leading prices.
Zirconia (ZrO2 & Zirconium Oxide) is a unique Advanced Ceramic . Products manufactured from zirconia ceramic exhibit superior mechanical properties such as high strength and flexibility. Heat insulating properties and oxygen-ion conductivity indicate zirconia has potential for use in a wide variety of applications - everything from telecommunications to the new energy of the future and environmentally beneficial products.
Depending on doping material different material properties could be achieved because of influencing the Yttria's microstructure. The "Ceramic Steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.
Features of zirconia ceramic sealing ring:
1. High hardness, good wear resistance, small thermal conductivity, good chemical stability and high corrosion resistance.
2. High fire resistance.Can withstand temperatures up to 1500 ℃
3. Good chemical stability. It can resist acid corrosion at high temperature.
4. Strong strength, abrasion resistance, good chemical stability, good biocompatibility and high density.
5. It is a kind of inorganic non-metallic material with high temperature, abrasion resistance and corrosion resistance. It is one
of the best refractory materials in nature.
The products are made of high purity Zirconia ceramics (Zro₂) and Alumina Ceramics (Al₂O₃) material, which have
advanced and excellent performances, fabulously popular .
