Title (EN) IMPROVED STABILIZED ZIRCONIA
(FR) ZIRCONE AMELIOREE ET STABILISEE
Abstract: front page image
(EN)The invention is directed to improved stabilized zirconia compositions and the processes for making the same. Low cost stabilizers, in the form of ceria/yttria or ceria/yttria/neodymium mixtures, are used to maintain zirconia in tetragonal form at room temperature without tending to convert back to monoclinic form at increased temperatures or while under stress.
(FR)L'invention concerne des compositions de zircone améliorées et stabilisées et des procédés permettant de les fabriquer. On utilise des stabilisants de faible coût, tels que des mélanges oxyde cérique/yttria ou oxyde cérique/yttria/neodymium pour maintenir la zircone sous forme tétragonale à température ambiante sans qu'elle tende à revenir à sa forme monoclinique aux températures supérieures ou lorsqu'elle est soumise à des contraintes.
