Corundum Refractory Bricks vs High-Alumina Bricks: Why >90% Alumina Matters in Metallurgical Furnaces

In high-temperature metallurgical furnace applications, standard high-alumina bricks (typically <85% Al₂O₃) often fail prematurely due to acid-base corrosion, poor wear resistance, and short service life. Corundum refractory bricks—featuring over 90% alumina content and a dominant corundum phase—deliver 30%+ higher cold crushing strength, fire resistance exceeding 1700°C, and significantly enhanced erosion resistance. This technical advantage directly addresses common industry pain points: frequent lining damage and costly downtime. Learn how crystalline structure, manufacturing process (sintered vs. fused), and real-world performance in steelmaking and glass melting environments make high-purity corundum bricks the optimal choice for extended equipment life and reduced maintenance costs.
