|Title:||Structure And Properties Of Water Free Nd2o3 Doped Low Silica Calcium Aluminate Glasses|
|Abstract:||In this work, Nd2O3 doped low silica calcium aluminate glasses have been melted under vacuum conditions. Measurements of thermal diffusivity, density, optical absorption coefficient, glass transformation temperature (Tg), crystallisation temperature (Tx), dilatometric softening temperature (Td) and Vickers microhardness have been carried out. The results provided information about the sample's structure and showed that for Nd2O3 concentration up to 5 wt% there was no devitrification of the samples. The decrease in hardness and thermal diffusivity was about 8%, while the density increased about 8% with the increasing concentration of Nd2O3. The thermomechanical properties combined with their quantum efficiency indicate that this material is a candidate for an active medium for solid-state lasers.|
