Исследование процессов консолидирования керамики на основе оксида и нитрида алюминия и свойств спеченной керамики

Abstract

Ceramic sintering on the basis of Al[2]O[3] activated by nanopowder additives Al and submicron powder TiO[2] into a blend and applying the technology of spark plasma sintering (SPS) has been studied. The given paper shows that adding nanopowder Al in the amount of up to 5 wt. % into the powder Al[2]O[3] activates the sintering process and, as a result, leads to the increase in density and microhardness of sintered alumina ceramics. The study has revealed a significant effect of alumina ceramic density growth which is due to introducing the submicron powder TiO[2] to the initial blends composition.
