There’re black spots in white fused alumina, may be because the impurities it carries are not removed clean. Rust is a more common magazine, because the white fused alumina raw material itself exists iron oxide, if not removed clean, there will be black spots. In addition, in the production process, because the mechanical rust will also accidentally incorporated rust, eventually leading to the color of white corundum is not pure.
Production elastic abrasive blocks are not limited to white fused alumina, but also can be used with other abrasives, such as: brown fused alumina, black silicon caebide, green silicon carbide, diamond, etc.
The special process of tabular alumina determines its unique properties: high refractoriness; high corrosion resistance; high erosion resistance; high thermal shock resistance stability; high strength and good toughness; stable chemical properties. It is an ideal material for refractory, ceramic and electrical insulation, and it is also an ideal material for abrasives and polishing.
Compared with brown corundum, white corundum has higher purity and greater hardness than brown corundum, and it will not color the surface of the workpiece during polishing and other operations. It has many advantages that brown corundum does not have. Why can’t white corundum replace brown corundum? The editor of Haixu Abrasives will introduce it to you.
The difference between fused corundum and tabular alumina Fused corundum is generally used in refractory materials such as white corundum, sub-white corundum, and brown corundum, and is made of fused alumina or bauxite. What are the differences?
