Abstract
Abstract In this paper we have studied the properties of ZnO ceramics sintered from the ZnO-Zn nanopowders (NPs) produced by a pulsed electron beam evaporation of heterogeneous targets (oxide or metal) and to establish the influence of NPs prehistory on the luminescence and dilatometry properties of ceramics produced from them. Pressing was performed on uniaxial presses: static and the magnetic pulsed one. Sintering of ceramics was produced in air by heating to 1200 °C in 60 min. Maximal density of the ceramics did not exceed 81,25% of the theoretical density. The behavior of the shrinkage curves of ZnO-Zn NPs depends on their prehistory. Evolution of properties of ZnO-Zn nanoparticles (NPles) during annealing in air is studied by XRD and pulsed cathodoluminescence methods. The suppression of the ultraviolet emission in NP obtained by electron beam evaporation, and in ceramics sintered of them was established.
