White Tabular Corundum

Advantages

1. Extremely high purity and stable chemical composition
White tabular corundum is made by sintering high-purity industrial alumina at high temperatures above 1900 ° C. Finished materials typically contain over 99% Al₂O₃, providing excellent chemical stability and the lowest impurity content.

2. Fire resistance and thermal stability
Its dense crystal structure enables it to withstand continuous exposure to extremely high temperatures without significant deformation or degradation. Its excellent thermal shock resistance makes it suitable for furnace linings, kiln furniture, and refractory castables that undergo rapid heating and cooling cycles.

3. Excellent mechanical strength
Compared with traditional alumina aggregates, our product has excellent compressive strength, hardness, and impact resistance. These mechanical properties enable refractory products to maintain structural integrity under heavy mechanical loads, grinding environments, and repeated operational stresses, significantly extending equipment service life.

4. Low porosity and high packing density
During the sintering process, the material will form a dense microstructure with low porosity and high packing density. This feature reduces slag infiltration, minimizes molten metal infiltration, and improves chemical corrosion resistance. Therefore, even under harsh industrial conditions, refractory lining remains durable.

5. Long service life and low maintenance cost
Due to the combination of thermal stability, mechanical durability, and corrosion resistance, our Huao's products can help reduce the frequency of refractory material replacement and maintenance downtime. This translates into reducing operating costs, improving production efficiency, and enhancing the long-term reliability of industrial facilities.
 

Application

1. High performance refractory materials
It is widely used as a high-quality aggregate and filler in refractory bricks, low cement castables, self flowing castables, spraying materials, and prefabricated refractory components. Its excellent fire resistance improves the overall performance of the lining operating in extreme high temperature environments.

2. Steel industry
Steel plants use it for ladles, intermediate ladles, electric arc furnaces, blast furnace runners, reheating furnaces, and continuous casting systems. This material enhances its resistance to corrosion from molten steel, slag, and thermal cycling, ensuring stable operation and longer service life of refractory materials.

3. Cement and lime production
In cement rotary kilns, clinker coolers, calcination systems, and lime kilns, it effectively withstands abrasive raw materials and fluctuating temperatures, while reducing maintenance requirements and improving production continuity.

4. Petrochemical and chemical processing
Its excellent chemical inertness makes it suitable for refractory lining in petrochemical reactors, cracking furnaces, gasifiers, and chemical processing equipment. Its corrosion resistance helps to improve operational safety and equipment lifespan.
5. Casting, glass, and other high-temperature industries
White tabular corundum is widely used in glass furnaces, foundries, non-ferrous metal processing, waste incineration facilities, and other high-temperature industrial systems. Its stable physical properties, thermal shock resistance, and excellent corrosion resistance ensure reliable performance in continuously demanding operating environments, while supporting higher productivity and lower lifecycle costs.
