Products Description
Zirconia Ceramic tube
Zirconia ceramic tubes are stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. It offers low thermal conductivity and are electrical conductors above 800 centigrade degrees, it has excellent chemical inertness and corrosion resistance at high temperature of 2200 centigrade degrees.
Advantage
