Abstract |

[DE] Die Erfindung betrifft ein Verfahren zur Herstellung einer lithiumstabilisierten Me-ß''-Al¶2¶O¶3¶-Keramik, wobei Me für Lithium, Natrium, Kalium, Rubidium, Caesium, Kupfer, Silber oder Tantal steht. Die Herstellung erfolgt durch Brennen einer Mischung folgender Ausgangsstoffe: DOLLAR A - Lithiumaluminat des Typs Li¶2¶O x nAl¶2¶O¶3¶ mit n = 1, DOLLAR A - ein Aluminat des Typs Me¶2¶O x nAl¶2¶O¶3¶ mit n = 1, und DOLLAR A - gamma-Al¶2¶O¶3¶.
[EN] Lithium-stabilized metal beta-double-prime-alumina ceramic production comprises firing a mixture of the metal aluminate with lithium aluminate and psi -alumina. A lithium-stabilized Me- beta -Al2O3 ceramic is produced by firing a mixture of a lithium aluminate (Li2O.Al2O3), a metal aluminate (Me2O.Al2O3) and psi -Al2O3, where Me = sodium, potassium, rubidium, cesium, copper, lithium, silver or tantalum. Preferred Features: The starting materials are mixed in a stoichiometric ratio and, prior to sintering, are formed to: (a) a molded body by molding and/or pressing or injection molding; (b) a 1-100 mu m thick layer by screen printing; or (c) a 20 mu m to 2 mm thick foil by a foil drawing technique. After sintering, the product may be ion exchanged with nitrosyl cations to obtain a lithium-stabilized NO<+>- beta -Al2O3 ceramic. |
