Study of High-Density Zn-Doped Tungsten Trioxide Ceramic Targets

Abstract:

This paper deals with the preparation of zinc oxide doped tungsten oxide target by sintering in oxygenated flow atmosphere. The effect of the composition and the sintering conditions on the properties and microstructures of the targets has been studied. The optimal sintering conditions were found. The sintered zinc doped tungsten oxide ceramic target can achieve a relative density of 99.58%, a bending strength of 31.79MPa and a Vickers hardness of 349MPa.
