The invention relates to a rod-shaped composite target,nformed of ceramic powders and intended to be evaporated under a bundlenof electrons, comprising zirconia and at least one stabilizer of thenzirconia.n n n Characteristically, said target is characterized in thatnsaid zirconia stabilizer is included with a molar contentnbetween 2 and 30% and in that said zirconia is formed at more thann90% of a monoclinic phase.n n n Application to the manufacture of a low thermal barriernthermal conductivity and high thermomechanical resistance innceramic formed by evaporation under electron beam. |
