Sub-white refractory fused alumina is electrically fused at high temperatures within an arc furnace in a process that is very similar to that of brown fused alumina production. It features a hardness similar to white fused alumina and has a high degree of toughness. The material is recommended for use in bonded and monolithic refractory industries.

This material is also electrically fused at a high temperature in an arc furnace by the similar process of Brown fused alumina. It has the hardness like White fused alumina, and also has the high toughness as brown fused alumina. This materials is recommended especially for use of bonded and monolithic refractories industry. Available in group sizes and split sizes as per requested.
