Abstract: The A-Site and B-Site non-stoichiometry and sintering characteristics of (Sr1− x Lax )1− y Ti1− z O3 perovskites were studied using samples prepared by solid-state mixing. A-Site or B-Site deficiency was observed for La-doped SrTiO3 perovskites, and this increased with increasing La content. For A-Site deficient (Sr1 − x Lax )1 − y TiO3 perovskites, the cell volumes decreased although the reverse was observed for B-Site deficient (Sr1 − x Lax )Ti1 − z O3 perovskites. This may be related to number of B-Site vacancies in the perovskites through charge compensation. It was found that A-Site and B-Site deficiencies increase the density of (Sr1 − x Lax )1 − y Ti1 − z O3 perovskites. These characteristics may prove useful in the development of solid oxide fuel cell interconnect materials.
