Name: Black Zirconia Ceramic Block With Good Heat Insula
The thermal conductivity of zirconia ceramics is 2-2.2W/ m*k, and the thermal conductivity of stainless steel is about 35-40W/ m*k. Therefore, zirconia has good thermal insulation properties, and is often used as sensor accessories or probe fittings.
Wear resistance of zirconia ceramic is good, and very stable chemical properties, even in the high temperature of the acid-base environment, still will not react with other chemicals, making its application range is greatly increased, especially in the aerospace industry and sensor, is a kind of material which can not be replaced.
Black zirconia ceramic blocks are excellent products of zirconia ceramics, and the forming methods of zirconia ceramic parts are cold isostatic pressing, dry pressing and hot die casting.
