Zirconia ceramic tubes are stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. Zirconia ceramic tubes offer 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.
Use temperature up to 2400 centigrade degrees.
Low thermal conductivity
Resistance to molten metals
Good wear resistance
High fracture toughness
