Insulating ceramics Zirconia ceramics
Product Overview
The material of insulating ceramics is zirconia ceramic with high toughness, heat resistance, corrosion resistance, and wear resistance. The material of zirconia precision ceramic parts is a high insulating layer, which is incomparable to other metal materials and plastics.
The wear resistance of zirconia ceramics is 15 times that of alumina ceramics. The friction index of zirconia ceramics is only half that of alumina ceramics, while the friction index of its own alumina ceramics is lower. Second, the relative density of the zirconia ceramic ring is relatively high. After grinding and polishing, the color is bright and clean, it is mirror glass, and the friction resistance is small.
Product parameter table
Witter Ceramics is a professional manufacturer of insulating ceramics.
Insulating ceramics made of zirconia are mainly used as protection tubes and insulation tubes for thermocouple thermometers of temperature measuring instruments; at the same time, they can also be used for industrial resistance furnaces, experimental electric furnaces and heat treatment furnace tubes. In addition, zirconia ceramic parts should be used as basic parts for steel chemical analysis of fixed carbon tubes and fixed sulfur tubes, as well as other high temperature resistant, acid and alkali resistant insulating instrument components.
