Искровое плазменное спекание прозрачной Lu2O3 керамики

Abstract

In this work, we report on the fabrication of transparent lutetium oxide (Lu2O3) ceramics using spark plasma sintering method by the various kinds of nanoparticles and compact. The nanopowder of Lu2O3 produced by laser ablation was used as starting material. All the samples were sintered at 1450 °C and 48 MPa for 40 min. Sintering of Lu2O3 powder of monoclinic, cubic phase and compact led to a fully dense ceramics with an optical transmittance of over 78% at the wavelength of 1080 nm.
