High Purity Tabular Corundum With High Bulk Density

Product Description

HUAO Tabular Corundum is a white particle or powder material produced from high-purity alumina through fine grinding, rolling forming, and ultra-high-temperature sintering. Operating two production lines with an annual capacity of 100,000 tons, HUAO delivers tabular alumina products whose core performance indexes consistently exceed national quality standards.
Featuring a dense crystalline alpha-Al₂O₃ structure, it serves as an indispensable raw material for high performance shaped refractories, unshaped castables, and specialized industrial ceramics.

Technical Parameters

Various particle size fractions and powders can be prepared according to specific client requirements.

Key Features

• It has excellent fire resistance, outstanding corrosion resistance, and high abrasion resistance under heat and abrasion.
• Delivers a bulk density of ≥ 3.50 g/cm³ with excellent volume stability following high-temperature firing.
• Having low water absorption, it can significantly reduce the amount of water required in the castable mixture and the amount of binder in the formed refractory material.
• Apparent porosity controlled at ≤ 5.0% minimizes slag infiltration and prevents molten chemical erosion across diverse atmospheric environments.
• The uniform particle and flake shapes increase the packing density and improve the flowability of the castable mixture during the pouring process.

Advantages

• Reduced Thermal Stress Damage: Excellent thermal shock stability and toughness can protect the furnace lining from cracking or peeling caused by rapid temperature changes during operation.
• Optimized Castable Processing: Uniformly shaped particles significantly improve workability, ensuring that the castable can be dense and pore free.
• Consistent Large-Scale Supply: Backed by a 100,000-ton annual production capacity across dual manufacturing lines, HUAO guarantees reliable batch-to-batch quality and timely global delivery.
• Enhanced Refractory Lifespan: Ultra-low impurity levels (Fe₂O₃ ≤ 0.02%, SiO₂ ≤ 0.09%) maximize hot crushing strength, reducing maintenance shutdowns and overall material costs.

Applications

Tabular Corundum is widely used as a core structural aggregate and fine matrix filler in high-temperature furnace linings, prefabricated profiles, and integral castables in the steel, glass, ceramic, and petrochemical industries. It also plays an important role in the manufacture of efficient continuous casting functional refractory materials, including sliding door panels, blow plug cores, and induction furnace linings. These refractory materials are designed for extreme thermal shock and slag erosion resistance.
