Title
(EN) CRYSTALLINE TERNARY CERAMIC PRECURSORS
(FR) PRÉCURSEURS DE CÉRAMIQUE TERNAIRE CRISTALLINE
Abstract
(EN)
A method of forming Mn+1AXn, where M is an early transition metal (such as Ti) or mixtures thereof, A is a group III or IV element (such as Si) or mixtures thereof and X is C, N or mixtures thereof, the method comprising the steps of providing a precursor of formula Mn+1AXn and reacting the Mn+1Xn with A to provide Mn+1AXn. The Mn+1Xn may be ordered and/or twinned (eg by mechanical alloying, thermal treatment etc. prior to reacting with A, ordered and/or twinned during its formation from M and X. A may be present during the formation of Mn+1Xn from M and X or during the ordering and/or twinning of disordered Mn+1Xn. The Mn+1 AXn produced is substantially free from MX and or other residual phases.
(FR)
La présente invention concerne un procédé de formation de Mn+1AXn, dans laquelle M est un métal de transition précoce (tel que Ti) ou des mélanges de celui-ci; A est un élément de groupe III ou IV (tel que Si) ou des mélanges de celui-ci; et X est C, N ou des mélanges de ceux-ci, le procédé comprenant les étapes suivantes: la mise à disposition d'un précurseur de formule Mn+1AXn et la réaction du Mn+1Xn avec A pour obtenir MAn+1AXn. Le Mn+1Xn peut être ordonné et/ou jmaclé (par exemple, par alliage mécanique, traitement thermique ou analogues préalablement à sa réaction avec A, ordonné et/ou maclé pendant sa formation à partir de M et X. A peut être présent pendant la formation de Mn+1Xn à partir de M et X ou pendant l'ordonnancement et/ou le maclage de Mn+1Xn désordonné. Le Mn+1 AXn produit est sensiblement exempt de MX et/ou d'autres phases résiduelles.
