ABSTRACT:
The invention relates to dry heterogeneous refractory compositions comprising 90 to 30% by weight of a chamotte or grog and 10 to 70% by weight of a fine part comprising from 0 to 70% of weight of corundum or alumina and from 30 to 100% by weight of a substance comprising at least 70% by weight of zirconia, the said fine part having a silica content of less than 30% of its zirconia content, the percentages by weight of chamotte and of the fine part being stated with reference to the total weight of these two constituents, and the composition of the fine part being adapted to the chamotte so that the final material possesses in use a homogeneous resistance to chemical corrosion and to mechanical wear. These compositions are useful for the preparation of agglomerated refractory articles and of unshaped refractory products.
