Preparation of transparent ceramics yag dope for lanthanides

摘要

P the present invention relates to a process for the preparation of a ceramic material, transparent, based on an intermetallic oxide, which comprises: (a) synthesis of the particles (p) on the basis of the intermetallic oxide, by oxidizing calcination of particles (p0) containing a homogeneous mixture of organic salts of the various metallic cations of the intermetallic oxide; (b) the production of a molded material (m) on the basis of the particles (p) thus obtained, using the technique of the pressing filtering; and (c) the heat treatment (sintering) of the molded material (m) [invention also relates to the materials based on oxides are obtained according to this process, in particular, the transparent ceramic materials based on y3al5o12 (yag) of the lanthanides such as doped with neodymium, and their uses, in particular, by way of a material for amplifying laser. / p
