Pure LaCrO3 was synthesized from the mixture of La2O3 and Cr hydroxide under hydrothermal conditions of 100 MPa at temperatures as low as 700°C. Synthesized specimen of LaCrO3 consisted of homogeneous fine grains with the size of 0.7±0.2 µm. These grains were subsequently sintered by using hydrothermal reactions to remove H2O as the form of H2. A fine-grained and well-sintered body could be obtained under 100 MPa at 1000°C or above.
