Effect of oxide additives on the sintering behavior and electrical properties of strontium- and magnesium-doped lanthanum gallate

Low-temperature sintering and electrical properties of strontium- and magnesium-doped lanthanum gallate with V2O5 additive

“…The design of sintering aids to promote densification can be a practical alternative. In a previous report [27], 1 at.% of 14 different oxide additives was added to LSGM and their effects on the sintering behaviour was examined. The addition of V, Zn, Si, Co, and Fe improved the densification and a.c. electrical conductivity at 300 • C, with V showing the most promising effect.…”

Approaches for the preparation of dense ceramics and sintering aids for Sr/Mg doped lanthanum gallate: focus review

“…The nature of the alloying metal and the concentration of the additive determine the ceramic grain size, phase stability, material density, total conductivity, and grain boundary resistance. Ha et al [69] investigated a series of 1 % additives introduced via metal nitrates into La0.8Sr0.2Ga0.8Mg0.2O3−δ powder. The best results for ceramic densification at 1300 °C were achieved by the addition of V 5+ , Li + , and Cu 2+ ions, for phase purity by the addition of B 3+ , V 5+ , and Si 4+ , and for electrical conductivity by the addition of V 5+ , Fe 3+ , Zn 2+ , and Cu 2+ .…”

State of Chromium Atoms, Clustering, and Interatomic Interactions in Doped Lanthanum Gallate La(Sr)Ga(Cr,Mg)O3-δ

“…At the same time in some works the effects of stabilization of the structure of lanthanum gallate doped with Sr and (or) Mg were found upon introduction of transition element ions [40,41].…”
