Zirconia (ZrO2) Ceramics have the highest toughness and strength at room temperature of all the advanced ceramic materials. At present, it has been widely used in grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant knives, and other room-temperature resistant Grinding parts and so on. Zirconia is widely used in the fields of the thermal barrier layer, catalyst body, medical treatment, health care, textile, and so on. This dense advanced ceramics material is usually precision ground using conventional diamond cutters and wheels. Machines used for precision grinding include: Surface grinders CNC milling machines Jig grinders Centerless grinders CNC lathes ID grinders

Mo Mn Ceramic Feedthrough Ceramic Vacuum Electrodes The Ceramic Surfaces for Brazing, the surface must be metallized. Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher. Advantages of Ceramic-to-Metal Seals * More solid, durable hermetic seal and better electrical insulation * Used for more harsh conditions, such as high and low (cryogenic) temperature, corrosive, high pressure, and high vacuum environments * High mechanical strength, less fracture when applied to high vibration and high g-load conditions * Shows strong bond and an excellent seal with metals and alloys, such as copper and Cu alloys (CuNi) and to nickel and Ni alloys.

Technical ceramics are favoured in a wide range of electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Ceramics have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard, and have excellent dimensional stability. Al2O3 Properties: Excellent electrical insulation Relatively low strength and fracture toughness Resistance to wear and corrosive Excellent thermal stability Resistance to high temperatures High electrical resistivity Good chemical stability High corrosion resistance
