The fused white corundum is made up of 1mm-200 mesh particle and the mesh fine powder of 200 mesh -1000, and by weight hundred in the dispensing Divide includes than meter：1mm-200 mesh particle fused white corundum 0-15%, the mesh fine powder fused white corundum 0-15% of 200 mesh -1000；
α-the Al2O3Micro mist and all mesh fine powders of 200 mesh -1000 of Guangxi white clay；
In the fused white corundum composition：Alundum (Al2O3) ＞ 98.5%, in the electrofused mullite composition：68% ＜ tri- is aoxidized Two aluminium ＜ 75%, di-iron trioxide ＜ 0.5%；
2) more than 200 but the not dispensing including 200 mesh are first added into planetary kolleroang, then 70% bonding agent is added into planet Formula kolleroang mixed grind, then adds remaining dispensing and mixed grind is uniform, and mixed grind is uniformly released pug and stands 24 hours afterwards, then Pug after standing is rejoined into planetary kolleroang, then to adding remaining bonding agent in planetary kolleroang and stir It is well mixed, finally it is made adobe with brickmaking machine；
3) obtained adobe is entered into klining knot, is got product.
