Mingrui focuses on the research, development and production of zirconia ceramic structural parts, and has supplied zirconia ceramic products to many enterprises in different countries.
Zirconia ceramics, ZrO2 ceramics, zirconia ceramic with high melting point and boiling point, hardness, insulation at room temperature, and high temperature has electrical conductivity and other excellent properties. Zirconia ceramics is a new type of ceramics, which are mainly divided into three types:
Magnesium stabilized zirconia ceramics (Mg-ZrO2)
Cerium stabilized zirconia(ZrO2 + CeO)
Yttrium stabilized zirconia(YSZ)
