PCT No. PCT/FR92/00835 Sec. 371 Date Jun. 14, 1994 Sec. 102(e) Date Jun. 14, 1994 PCT Filed Sep. 1, 1992 PCT Pub. No. WO93/05195 PCT Pub. Date Mar. 11, 1993.The target element (2) is formed from an inorganic compound layer (16) with a melting point above 300 DEG C. deposited on a foam or metallic felt support layer such that the layer of inorganic compound sinks to part of its depth into the support layer to define a composite layer (17). In order to form the target element, a precursor system of the inorganic compound is applied to the support layer, the assembly so formed is subjected to a pressure of between 0.1 MPa and 15 MPa, the resulting assembly is maintained at between 300 DEG C. and 1600 DEG C. and below the melting temperature of the support in order to obtain a sintered assembly. Said assembly is than cooled to an ambient temperature avoiding any sudden cooling. In order to produce the target, the element (2) is glued to a metallic substrate (4) using a conductive adhesive.
