Typical Physical Properties of High Temperature Treated BFA
01.
Eliminate Abnormal Expansion
Calcination of brown fused alumina will produce abnormal expansion, which will lead to grid cracks on its surface, while calcination can eliminate abnormal expansion and reduce the formation of
waste.
02.
Improve Toughness And Grinding Performance
The calcined brown fused aluminium oxide has a hard reaction inside, the compressive strength is enhanced, and the durability and sharpness are greatly improved.
03.
Improve Hydrophilicity
The hydrophilic performance of the calcined brown fused alumina is more than doubled.
04.
Improve Strength of Abrasive Tool
The specific surface area of the brown fused alumina particles after high temperature calcination is greatly increased, so the abrasive and the cloth base are much stronger.
05.
Improved Durability
The durability of calcined brown fused alumina is more than 40% higher than that of ordinary brown fused alumina.
06.
Improve Appearance And Cutting Ability
After the brown fused alumina is calcined, the magnetic substance inside is reduced, reducing the probability of rust spots on the surface.
