            Objetivo de tungstenos

                Tungsten-Target

            A sintered tungsten target for sputtering, characterized in that it exhibits a relative density of 99 % or more, an average crystal grain diameter of 100 μm or less, an oxygen content of 20 ppm or less and a deflection force of 500 MPa or more&semi; and a method for preparing the Objetivo de tungsteno with stability at a low cost, which uses improved production conditions for a raw material Tungsteno en Polvo and improved sintering conditions. The sintered Objetivo de tungsteno has a high level of density and a high degree of the fineness of a crystal structure which have never been achieved by a conventional pressure sintering method and is markedly improved in deflection force, which has resulted in the significant decrease in the occurrence of particle defects.
