The present invention provides a ceramic material comprising: a first phase comprising zirconia, yttrium and cerium, wherein the yttrium and cerium are present in a molar ratio of 0.15 to 0.5 and in a combined amount of 5 to 15 mol %, a second phase comprising alumina, and a third phase comprising metal aluminate platelets.

Zirconia-alumina ceramic materials

The method is accomplished by having a casing affixed about the area of the equipment component or part subject to the abrasive wear. A wear-resistant concrete material is cast into the spacing between the casing and the surface of the equipment. A wear-resistant ceramic plate or steel plate can also be affixed to the surface of the equipment prior to casting the concrete in place.
