| titleOfInvention | Process for preparing ceramic bodies of fine crystalline structure |
| abstract | In the process of the present invention ceramic bodies are produced by activating and shrinking oxygen-containing inorganic aluminum compounds, preferably aluminum hydroxide, boehmite, gamma-aluminum oxide, or alpha-aluminum oxide or mixtures thereof. The invention is characterized by the addition of 0.05 Ό, 5 wt% yttrium oxide or lanthanum oxide, or neodinyl oxide or an equivalent amount of alumina, as an additive, to the oxide of the invention by heating to oxide. the mixture is homogenized by grinding and heat-treated at a temperature of at least 1450 ° C. Thus, at least 80 wt.% of the additives are reacted with the aluminum oxide, and then the two or three kinds of alumina oxides activated in this way are mixed and the resulting mixture of pure oxides, expressed as total of 0.1-1 wt. the finished ceramic materials are transformed into mold bodies in a manner known per se, and are subsequently shrunk at temperatures above 1450 ° C. -1- |
