An orthorhombic to a rhombohedral structural phase transition of LaCrO 3 has been studied by the neutron powder di4raction over the temperature range of 295+1013 K. At the phase transition around 2603C, the negative volume expansion was observed, and the amount of the volume compression was estimate
