Low heat conductivity zirkonoxidkeramik hard ceramic ring spacer
Product Description
Zirconia Ceramic:
In terms of functional ceramics, its excellent high temperature
resistance is used as an induction heating tube, refractory
material, and heating element. Zirconia ceramics have sensitive electrical performance parameters and are mainly
used in oxygen sensors, solid oxide fuel cells (SOFC) and high
temperature heating bodies.
In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of
their high toughness, high flexural strength and high wear
resistance, excellent thermal insulation properties, and thermal
expansion coefficient close to that of steel.
