Magnesia Stabilized Zirconia Crucible (MSZ Crucible)

Product Code :

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 (220C 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, ATT’s partially stabilized MSZ provides excellent strength, toughness, wear, abrasion, and corrosion resistant materials to meet the severe service needs of many industries.

Magnesia stabilized zirconia exhibits superior resistance to thermal shock and erosion. It has low thermal expansion properties and excellent non-wetting characteristics. Zirconia (ZrO2) Crucibles are great refractory and insulating materials. They have a clean melt at temperatures above 1900°C and above and are specially manufactured for melting superalloys and precious metals. They also have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis.

MSZ Machining

MSZ can be machined in green, biscuit, or fully dense states. While in the green or biscuit form, it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the zirconia body to shrink approximately 20%. This shrinkage means that it is impossible to hold very tight tolerances when machining zirconia pre-sintering. In order to achieve very tight tolerances, the fully sintered material must be machined/ground with diamond tools. In this manufacturing process, a very precise diamond coated tool/wheel is used to abrade away the material until the desired form is created. Due to the inherent toughness and hardness of the material, this can be a time consuming and costly process.
