Synthesis and Characterization of Sr‐ and Mg‐Doped LaGaO 3 Tapes
Source abstract
Abstract
The study focuses the processing of La 1− x Sr x Ga 1− y Mg y O 3− d (LSGM) tapes and the characterization of their microstructure, chemical composition, and sinter behavior during annealing. Dilatometric runs show that sintering of the tapes conclude at about 1500°C. This finding correlates with the observed sharp increase of the crystallinity of LSGM at higher temperatures. The porosity of the tapes has been found to be minimum at 1525°C. Increasing sintering temperatures cause a loss of Sr, Mg, and Ga, which is presumably due to evaporation of the elements. The Vickers hardness of the tapes sintered at 1500°C was measured to be about 900.
