Ceramic insulator

Product Overview Magnesium Stabilized Zirconia (MSZ) is a refractory ceramic material capable of withstanding ultra-high temperatures up to 2200°C. It is primarily composed of zirconium oxide (≥95%) and is distinct from white zirconia ceramics (Y2O3 partially stabilized zirconia). MSZ is characterized by its yellow color and porosity, and is available in two types: one with low porosity (density ≤5.2 g/cm3) and one with higher porosity (density 5.4-5.6 g/cm3). Both types can be used in air, vacuum, or protective atmosphere environments.
