Product Description

Refractory Quartz Bricks, Alumina Mullite, and Corundum BricksCorundum refractory brick is crafted for high temperatures, primarily of α-Al2O3 (≥90% content). It delivers exceptional heat resistance (≥1750℃ limit), remarkable strength (80-150MPa compressive), and superb erosion resistance. Ideal for challenging environments like steel metallurgy and glass kilns.SpecificationKey Features & Advantages
Unmatched Heat Resistance: Withstands up to 1800°C, ideal for high-temp melting and sintering.
Thermal Shock Resilience: Prevents cracking during rapid heating/cooling, enhancing durability.
Chemical Stability: Inert in oxidizing/reducing atmospheres (H2, CO, vapor), perfect for precise analysis.
High Mechanical Strength: Ensures integrity and insulation under extreme conditions.

Applications
Laboratory Analysis: Melts metals/non-metals for XRF, ICP, AA with minimal contamination.
Alloy Smelting: Maintains purity by resisting slag and impurities.
Industrial Furnaces: For ceramic, glass, and semiconductor production, ensuring consistent results.
