Medium Temperature Calcined Brown Fused Alumina

1. Description:

♦ Through calcination, the impurities are vaporized and the surface of abrasives become more pure and rough. Meanwhile, the abrasives become more hydrophilic.

♦ Medium Temperature Calcined Brown Fused Alumina/Medium Heating Brown Fused Alumina is the processing  with brown fused alumina above in high temperature heating(1000°C).

♦The crackles are engendered after calcination, increasing the toughness and hardness of abrasives.

2. Applications:

♦ High-speed intensity sand belts

♦ High-loading grinding wheels

♦ Top grade bonded abrasive tools

♦ Coated abrasives and sand blasting
