  • Oxide refractory material having fine crystal structure; and process and apparatus for making same
    Patent number: 4439895
    Abstract: Oxide refractory materials (for example, alumina-zirconia mixtures) can be cast to have an extremely fine crystal structure by casting them onto a non-reactive, non-melting particulate solid cooling media of a material other than that of the oxide refractory material (for example, steel spheres having a size ranging from about 5 to about 60 mm). By using steel spheres as the cooling media, the spheres can be removed from the solidified material with a magnet. The solidified material, when crushed and graded, has exceptional utility as an extremely tough abrasive grain.
    Type: Grant
