Magnesia Stabilized Zirconia Crucible Description

Transformation toughened zirconias such a magnesia stabilized zirconia have small precipitates of tetragonal phase which are formed inside of the cubic phase grains. These precipitates transform from the meta-stable tetragonal phase to the stable monoclinic phase when a crack attempts to propagate through the material. This causes the precipitate to expand and blunt the crack tip promoting toughness.

MSZ can be either ivory or yellow-orange in color due to differences in preparation of the raw material. Ivory colored MSZ has a higher purity and offers slightly better mechanical properties.

MSZ is more stable in high temperature (220℃ and above), high moisture environments than YTZP - where YTZP typically degrades. MSZ has a low thermal conductivity and CTE similar to cast iron to prevent thermal mismatch in ceramic to metal assemblies.

Due to the transformation toughening, our partially stabilized MSZ crucibles provide excellent strength, toughness, wear, abrasion, and corrosion resistant to meet the severe service needs of many industries.
