Abstract

A method for the preparation of a ceramic-metallic composition (cermet) consisting of at least 70% by weight of a solid material comprising from 35 to 70% by weight of a metallic nickel phase and from 65 to 30% by weight of at least one oxide selected from oxides of transition metals and lanthanides, comprising the following steps in succession: i) preparing a mixture of powders comprising metallic nickel and at least one oxide different from nickel oxide, selected from oxides of transition metals and lanthanides; ii) laying said mixture of powders on a suitable surface, in the form of a layer having a thickness ranging from 2 to 1500 µm; iii) heating said layer under oxidative conditions until obtaining the desired sintering degree; and, optionally, iv) reducing the nickel oxide in the sintered product to metallic Ni.
