| Other information |
| White fused alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size. It is recommended for refractory applications where purity, chemical stability or high refractoriness is an issue to be considered. |
