APPLICATION OF WHITE FUSED ALUMINA

1. White fused alumina is usually used for high grade refractory material, and also for ceramic, resin bonded abrasive grinding, sandblasting and precision casting.

2. Oilstone/polishing pad, grinding wheels etc.
3. Lapping, polishing, decorative non-skid tile, and pressure blasting.
4. Ceramic Tiles special ceramics.
5. Fluidized Bed Furnaces and Dental Care.
6. Using for making polishing paste/solution etc.
7. Anti-friction material, anti-resisting grounds/paper.
