Abstract: A process for treating a fused refractory product including more than 10% by mass of ZrO2, or “base product.” The process includes heating at least a portion of the surface of the product, so as to melt ZrO2 crystals in a superficial region extending to a depth of less than 2000 μm. The process includes cooling the molten superficial region obtained in the preceding step so as to obtain a protective layer.

Abstract: A process for the manufacture of a refractory block including more than 80% zirconia, in percentage by weight based on the oxides. The process includes the following successive stages: melting, under reducing conditions, of a charge including more than 50% zircon, in percentage by weight, such as to reduce the zircon and obtain a molten material, application of oxidizing conditions to the molten material, casting of the molten material, and cooling until at least partial solidification of the molten material in the form of a block. Also, the process can include heat treatment of the block.
