Brown Fused Alumina
Description
Brown fused alumina (BFA) is made of high-quality abrasive grade bauxite as raw material, together with auxiliary materials, refined in an electric arc furnace at a high temperature above 2250 ℃. On this basis, after the secondary refining, the impurities are removed by a high-intensity magnetic separator, and the refractoriness of the BFA is above 1850 °C.
Features
- High purity
- Good crystallinity
- Liquidity
- Low coefficient of linear expansion
- Preservative
