Among the ceramic materials, Zirconia ceramics have the lowest thermal conductivity, good thermal insulation, close to Metal Coefficient of thermal expansion, and are important structural materials, special crystal structure and phase transformation toughening of ZRO2, according to the stabilizer, yttrium stabilized Zirconia, magnesium stabilized Zirconia, cerium stabilized Zirconia, two-phase or multiphase stabilized Zirconia can be separated Widely used in medical food (ceramic pump valve, plunger, etc.) , biotechnology (denture, etc.) , daily accessories (smart wear) .
