Magnesium Stabilized Zirconia Powder MSZ zirconia powder stabilized with magnesium oxide (MgO).
Magnesium-stabilized zirconia (MSZ) powder is a zirconia powder stabilized with magnesium oxide (MgO). Its core advantages are high temperature resistance (up to 2200℃), thermal shock resistance, resistance to molten steel/slag erosion, and good ionic conductivity. It is primarily used in four major areas: metallurgical refractories, high-temperature structures, energy electronics, and protection.
