Scott W Pellow, Ronald W Trischuk, Christopher E Knapp, Ralph Bauer: Sintered alumina-zirconia ceramic bodies. Norton Company, Arthur A Loiselle Jr, October 2, 1990: US04960441 (82 worldwide citation)

Useful ceramic bodies can be made by mixing zirconia powder with seeded alumina gel, drying, and firing at a high enough temperature to convert the alumina in the gel to microcrystalline alpha alumina. Abrasive grits made in this way, with a zirconia content between 15 and 30 weight percent and at l ...

Ralph Bauer: Boehmite produced by a seeded hydyothermal process and ceramic bodies produced therefrom. Norton Company, Arthur A Loiselle Jr, January 10, 1989: US04797139 (80 worldwide citation)

Microcrystalline boehmite suitable for conversion to anhydrous alumina products is produced by hydrothermal treatment of precursor alumina raw material at controlled pH and in the presence of microcrystalline boehmite seed material. Reaction mix may include submicron seed material for seedling for l ...
