An x-ray diffraction analysis of the LaCrO₃-LaAlO₃ solid solution series

Author

Abstract

"A crystallographic study was made of powders from the LaCr_1-x Al_xO₃, La_.90(Mg_.05 Cr_1-x Al_x )_.95O_2.83 , and La_1±xCrO₃ systems. The relationships between composition and thermal expansion, electrical conductivity, and vaporization were also investigated. The x-ray diffraction data of the LaCrCO₃ - LaAlO₃ compounds showed the system to form a single phase solid solution for any given sample from the series. The orthorhombic to rhombohedral phase transition was depressed to below room temperature at approximately 13% Al⁺³ substitution"--Abstract, page ii.
