摘要：

High temperature x-ray diffractometry (HT-XRD) and differential scanning calorimetry (DSC) measurements confirm that two kinds of structural phase transitions exist in LaGaO3. One is the first order transition from the orthorhombic to the rhombohedral structure at approximately 150-degrees-C. The other is the second order transition from the rhombohedral to the monoclinic structure from approximately 750-degrees-C to approximately 1000-degrees-C.
