High-purity magnesia brick is a basic refractory material with a magnesia (MgO) content of over 96%, with periclase as the main crystalline phase. It exhibits excellent resistance to high-temperature corrosion and maintains good structural stability under severe operating conditions.
• Excellent resistance to slag corrosion
• Outstanding volume stability at high temperatures
• High refractoriness and good structural stability
