White fused alumina for refractory(WFA) is the raw material for the production of refractory materials. Also known as white corundum or white alumina. Compared with brown corundum, it is more uniform in chemical composition, structure and properties, and is a product with high hardness, high brittleness, high purity, high melting point and large crystal size. It is widely used in the refractory industry and can also be used in hundreds of applications such as ceramic profiles, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, grinding, polishing, grinding and more.
White Fused Alumina for Refractory is generally used for aggregates and fines. White corundum has the characteristics of high temperature resistance, corrosion resistance and wear resistance, and has good high temperature stability when making corundum products. The products of white corundum are corundum bricks, magnesia-alumina bricks, etc., which can be used as refractory materials for furnace tops.
Features Include:
Mohs hardness: 9 Bulk density:1.75-1.95g/cm3 Specific gravity:3.95g/cm3
Volume density:3.6 Melting degree:2250ºC Refractory degree:2000ºC
1. High purity - Made from pure alumina, which gives it a high degree of purity.
This purity is important in many industrial applications where contaminants can cause problems.
2. Hardness -a very hard abrasive, which makes it ideal for applications where a high degree of wear resistance is required.
3. Thermal stability - which makes it ideal for use in high-temperature applications such as furnaces and kilns.
4. Chemical stability -It has good chemical stability, which means it is resistant to acids and other corrosive substances.
