Features of Abrasive Powder
Crystal structure
White fused alumina belongs to the α-al₂o₃ crystal structure, with a hexagonal close-packed lattice, a dense structure, and strong stability.
Appearance:
In its natural state, it is white particles or powder. After being crushed, it presents angular shapes, with rough particle surfaces, which are conducive to combining with other materials.
Physical properties:
The mohs hardness is 9.0 (second only to diamond and silicon carbide), the density is approximately 3.9-4.0 g/cm³, the refractory temperature is as high as above 1800℃, the thermal conductivity is good, and the thermal expansion coefficient is small.
In the field of refractory materials: White fused alumina can be used as the core raw material of high-alumina refractory materials, and is used to produce shaped or non-shaped refractory materials.
In the fields of ceramics and electronics: High-purity alumina can be used to produce high-temperature structural ceramics (such as wear-resistant ceramic linings, ceramic tools), or electronic ceramics (such as integrated circuit substrates, insulating porcelain parts), taking advantage of its insulating and chemical stability.
Production Process of Abrasive Powder
Raw materials
The raw materials for producing fused alumina powder should be fine powder made by grinding first grade wfa blocks. The first level fixed furnace white fused alumina block is more excellent.
Grinding process
Grinding corundum blocks takes more than 20 hours. And the grinding medium is alumina balls. After grinding, the amount of white corundum powder is small, with a particle size range of 63 microns to 0.5 microns.
Overflow siphon process
The coarse white fused alumina powder 240mesh- 600mesh is classified using overflow classification method. The finer white fused powder 700 mesh – 10000 mesh production is a siphon process. More precise particle range control is beneficial for improving the uniformity of the powder.
Precipitation drying process
Natural precipitation is used to completely precipitate the powder suspension and remove moisture. Then, it is dried in a high-temperature kiln to control residual moisture. Finally, sieve and loosen the corundum powder to maintain its looseness and prevent agglomeration.
