White Corundum(WFA) is a high-purity synthetic material produced by the fusion of high-grade alumina in an electric arc furnace. With a purity of over 99% aluminum oxide (Al₂O₃), it exhibits exceptional hardness, high thermal stability, and resistance to chemical corrosion. Its uniform particle size distribution and angular structure make it ideal for precision abrasive applications. Additionally, its iron-free and low-sodium composition ensures minimal contamination, providing excellent performance in high-demand environments.
White corundum is manufactured through a meticulous process:
1. High-purity alumina is melted at a temperature exceeding 2000°C in an electric arc furnace.
2. The molten material is cooled, crystallized, and then crushed into a fine powder.
3. Advanced sieving and magnetic separation techniques are employed to remove impurities and achieve the desired grain sizes.
4. The final product undergoes rigorous quality testing to ensure consistency and compliance with industry standards.
For Refractories Application
White corundum is widely used in the production of advanced refractory materials due to its high melting point and excellent thermal conductivity. Key applications include:
• Castables and Monolithics: Enhances strength and resistance to thermal shock in high-temperature linings.
• Refractory Bricks: Provides durability and stability in furnaces, kilns, and reactors.
• Slide Gates and Nozzles: Offers wear resistance and longevity in steel-making processes.
Its purity and thermal stability make it indispensable in environments requiring consistent performance under extreme conditions.
