High-Purity Corundum Bricks – High-Temperature Refractory Material | 99% Alumina | Industrial Kiln Specialized

Description

High-purity corundum bricks are premium refractory materials made from 99%+ high-purity alumina (Al₂O₃), formed under high pressure and sintered at ultra-high temperatures. They exhibit excellent high-temperature resistance (≥1800°C), corrosion resistance, high strength, and low thermal conductivity, making them ideal for high-temperature industrial furnaces in steel, glass, chemical, and new energy industries.

Key Features

Ultra-High Purity – Al₂O₃ content ≥99%, resistant to chemical corrosion and slag erosion.
Extreme Heat Resistance – Refractoriness ≥1800°C, stable long-term performance.
High Mechanical Strength – Excellent thermal shock resistance, low risk of cracking.
Low Thermal Conductivity – Some variants offer thermal insulation for energy efficiency.
Long Service Life – Superior wear and erosion resistance, reducing maintenance costs.

Manufacturing Process

  1. Premium Raw Materials – High-purity alumina powder with strict impurity control

  2. High-Pressure Forming – Dry pressing/isostatic pressing/casting for dense structure

  3. High-Temperature Sintering – Fired at 1600°C~1800°C to form stable α-Al₂O₃ crystals

  4. Precision Machining – Grinding, drilling, and custom sizing for exact specifications.
