White Corundum A

    White corundum is an artificial material mainly composed of alumina, which has the characteristics of high hardness, high wear resistance, good chemical stability, and thermal stability. The color of white corundum is usually white or gray white, with a dense crystal structure and high tensile and compressive strength. Its hardness is second only to diamonds and sapphires, making it suitable for various high-precision machining needs. ‌

    Preparation process

    The preparation process of white corundum mainly includes steps such as raw material selection, melting, crystallization, and processing. Firstly, high-purity alumina is selected as the raw material, which is finely processed and mixed before being melted in a high-temperature electric arc furnace. During the smelting process, aluminum oxide is melted and crystallized into white corundum by controlling the temperature and atmosphere. Finally, white corundum products with different particle sizes and shapes are obtained through processing techniques such as crushing and grinding.
