Title (EN) TRANSPARENT MULTI-CATION CERAMIC AND METHOD OF MAKING
(FR) CERAMIQUE MULTI-CATIONIQUE TRANSPARENTE ET PROCEDE DE FABRICATION ASSOCIE
Abstract: front page image
(EN)A method of making a multi-cation ceramic having an average grain size of less than 1 micron is provided. The method includes the steps of providing at least a first material and a second material, wherein the first material comprises a first cation and the second material comprises a second cation, and wherein the first cation and the second cation are different from each other and each of the first material and the second material are nanopowders; forming a mixture comprising the first material and the second material; forming a green body from the mixture; and forming a dense multi-cation ceramic material comprising the first cation and the second cation, wherein the dense multi-cation ceramic material comprises a major phase comprising the first cation and the second cation and that is different from the first material and the second material. The multi-cation ceramic has a high density and high in-line transmission.
(FR)L'invention concerne un procédé de fabrication d'une céramique multi-cationique ayant une taille du grain moyenne inférieure à 1 micron. Le procédé consiste notamment à fournir au moins un premier matériau et un second matériau, le premier matériau comprenant un premier cation et le second matériau un second cation. Le premier et le second cations sont différents l'un de l'autre et chacun des premier et second matériaux est un nanopoudre. Le procédé consiste également à former un mélange comprenant le premier et le second matériaux; à former une ébauche crue à partir du mélange; et à former un matériau céramique multi-cationique dense comprenant le premier et le second cations, le matériau céramique multi-cationique dense comprenant une phase majeure renfermant le premier et le second cations qui diffère du premier et du second matériaux. La céramique multi-cationique présente une densité et une transmission en ligne élevées.
