N2 - A series of chromium lanthanum oxide with the formula LaC1-rMrO3 (M = Cu, Mg, Zn) was synthesized by a conventional solid state reaction at 1350°C and 1600°C for 2 h in air and flowing N2 amd Ar gas. The products were recognized as single phase with orthorhombic perovskite structure in chemical composition range of 0x0,2 for M = Cu and Zn and Ox 0.15 for M=Mg in LaC1-rMrO3. Sinterability was evidently improved by the substitution of divalent cations. The electrical conductivities increased with increasing the content of divalent cations substituted. This behavior was closely related to the formation of mixed valency state of Cr3+ and Cr4+ ions due to the substitution of divalent cation for Cr8+ ions in LaCrO3.
