Ceramic Sheet High Strength Insulator Alumina Zirconia Ceramic Sheet Plate
Ceramic sheet was producted of the technical ceramics with a high strength insulations.
Thermal Insulation versus Thermal Conductivity
When selecting a ceramic material for its thermal insulation capability, considerations must also be made regarding their thermal conductivity. Ceramco’s fully dense alumina exhibits a thermal conductivity rate almost ten times higher than zirconia. fully dense zirconia formulations offer the lowest thermal conductivity of all materials currently offered by mingrui.
