White corundum is produced using industrial alumina powder as its primary raw material. It undergoes a high-temperature smelting process in excess of 2000 degrees Celsius, followed by controlled cooling. Through subsequent stages of crushing, shaping, magnetic separation to remove iron impurities, and sieving, it is classified into various granularity. This meticulous process results in a material with a dense texture, remarkable hardness, and grains characterized by sharp angles. White corundum finds applications in the manufacturing of ceramics, and resin-bonded abrasives, as well as in processes such as grinding, polishing, sandblasting, and precision casting. Additionally, it is an integral component in the production of advanced refractories. In line with international standards, it is designated as "Wa," a nomenclature that is consistent with national standards. While it is predominantly exported, there is also a steady supply to domestic users.
Advantages of White Corundum Products
1. Preservation of Processing Parts' Color:
White corundum has a distinctive advantage in that it does not alter the color of the parts being processed. This makes it particularly valuable in industries where maintaining the original appearance of materials is crucial.
2. Iron Residue-Free Sandblasting:
It can be employed in processes where the presence of iron residue is strictly prohibited. This is particularly relevant in applications like precision manufacturing where even minute impurities can cause defects.
3. Micro-Powder Grade for Wet Operations:
The micro-powder grade of white corundum is highly suitable for wet sandblasting and polishing operations. It exhibits excellent flow characteristics in wet environments, enhancing the efficiency and precision of the process.
4. Efficiency and Quality in Processing:
White corundum enables fast processing without compromising the quality of the finished product. Its sharp-grained structure facilitates efficient material removal, contributing to higher productivity.
5. Low Iron Oxide Content for Strict Standards:
The presence of iron oxide in white corundum is exceptionally low, making it an ideal choice for operations where even trace amounts of iron impurities are not permissible, such as in aerospace or electronics industries.
6. Post-Pickling Purity Enhancement:
It can undergo pickling steps to further enhance its purity by removing any residual impurities. This additional refinement process ensures that the material meets the strictest quality standards.
White corundum stands out as a versatile and high-performance material in various industries. Its exceptional purity, hardness, and granular structure make it a cornerstone in processes demanding precision, quality, and reliability. Whether in ceramics, abrasives, casting, or refractories, white corundum consistently delivers exceptional results.
