Synthesis and crystal growth of La1−xSrxFeO3 have been studied under hydrothermal conditions. The optimum conditions to synthesize LaFeO3 were found to be 425–600°C with 50 wt% KOH solution under 100 MPa. LaFeO3 single crystals have been grown in those conditions up to 0.8 mm in diameter with the temperature gradient of 5°C for 168 h. The perovskite formation regions from the mixture of lanthanum oxide, iron oxide and SrCl2 solution of the composition La1−xSrxFeO3 (x=0.02, 0.10) were similar but a little narrower than those of LaFeO3. The hydrothermal crystal growth brought about the crystals of maximum 0.3 mm at x=0.02 and 0.03 mm at x=0.10.
