- Abstract
- The effects of 14 different metal-oxide additives (metal = Mn, Fe, Co, Ni, Cu, B, Li, V, Zn, Si, Ca, Al, Bi, and Ba) on the sintering, phase purity, and electrical properties of strontium- and magnesium-doped lanthanum gallate (LSGM) are studied. The density, phase purity, and electrical conductivity depend closely on the sintering aids and sintering temperatures. The addition of V, Zn, Si, Co, and Fe improves the densification, phase purity, and electrical conductivity, with V showing the most promising effect on the low-temperature sintering of the phase-pure LSGM specimen with high conductivity.
