Description

Transparent Nd-doped cubic Y2O3 ceramics have been prepared by magnetic pulse compaction of nano powders, followed by sintering. Analysis of the transport of nonequilibrium thermal phonons at liquid helium temperatures has been used to assess the effect of preparation conditions on the microstructure, average thickness, and stability of the grain boundaries in the ceramics. The average grain-boundary thickness in the transparent ceramics is shown to be comparable to the lattice parameter of Y2O3

Abstract (Russian)

Методом магнитно-импульсного прессования с последующим спеканием нанопорошков синтезированы образцы оптически прозрачной керамики на основе кубического оксида Y2О3 с Nd. Из анализа транспорта неравновесных тепловых фононов в области гелиевых температур установлена связь структуры, средних размеров и степени стабилизации межзеренных границ с технологическими условиями синтеза. Показано, что в оптически прозрачных образцах керамики средние толщины межзеренных границ сравнимы с постоянной решетки кристаллита Y2O3
