Magnesia-Stabilized Zirconia (MSZ) stands out as an exceptional refractory and insulating material, distinguished by its high oxygen ion conductivity, superior mechanical strength and toughness, and outstanding thermal shock resistance. With a clean melting profile above 1900°C, it is specifically engineered for demanding applications such as superalloy and precious metal melting. Moreover, it maintains remarkable thermal stability even at extreme temperatures up to 2200°C.
Key Characteristics:
- Exceptional resistance to thermal shock
- High wear and erosion resistance
- Strong corrosion resistance against molten metals at elevated temperatures
- Excellent non-wetting behavior
- Superior mechanical strength
- Long operational lifespan
The formulation of stabilizers and grain structure can be customized to align with specific customer operating conditions.
Operating Temperature Range: 0°C to 2200°C
Suitable Environments: Air, vacuum, or atmosphere-protected settings
