| (white fused alumina) FEPA#12 | |
| White Fused Alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved. | |
| Al2O3 | ≥99.55% |
| Fe2O3 | ≤0.04% |
| SiO2 | ≤0.04 |
| Na2O | ≤0.22% |
| （Bulk density） | 1.75-1.95g/cm3 |
| （Grain density） | ≥3.90g/cm3 min |
| （Morse hardness） | ≥9 |
| (Usage) | Refractory material; polishing material; Casting; Painting material; Grinding material; Sandblasting material,etc |
