The raw material of white aluminum oxide micro powder is white fused alumina, which is made of high-quality aluminum oxide powder. The main impurities in the bauxite are reduced by reduction smelting method, thereby obtaining brown corundum that is crystallized and has a quality that meets the requirements and an alumina content of greater than 95%. The product is white in color, harder and brittle than brown corundum, has stronger cutting force, good chemical stability, and good insulation. It is suitable for some advanced polishing and refractory materials.
Iron sand comes from extracts from lakes and reservoirs. After special production, it becomes fine particles. It is characterized by edges and high hardness. It can be used in heat treatment, refractory materials, rust removal, metallurgy, and sand cleaning. In related industries such as iron sand and white aluminum oxide, there are similarities in the raw materials. Among the raw materials of white fused alumina, bauxite accounts for the highest proportion, and the performance of white fused alumina after production is also characterized by wear resistance and high pressure.
The characteristics and scope of application of white aluminum oxide sand are particularly similar to those of iron sand. So why not use iron sand in white fused alumina raw materials? In fact, the production process of white fused alumina requires high-temperature forging. The performance of iron sand is unstable at high temperatures, and white aluminum oxide will also be exposed to the high-temperature calcination process in later use. For environments with high anti-corrosion requirements, it is more Iron sand cannot be used anymore. As we all know, iron will corrode after a long period of oxidation, which is very bad for later use.
