| 中文摘要 | a distorted layered perovskite compound batb2mn2o7 was synthesized by the solid state reaction in pure argon. there is a structural phase transition in the batb2mn2o7 compound. the phase transition was characterized by the dsc and high temperature xray diffraction. the heat capacity of batb2mn2o7 was calculated. the thermal anomaly corresponding to the phase transition was observed at about 740k. the lattice parameters were calculated by the cell program for batb2mn2o7, it has tb-type orthorhombic symmetry with a = 0.3908 nm, b = 0.3866 nm, c = 2.0163 nm, and space group immm at room temperature. with the increase of temperature, the lattice parameters gradually increase until 673k. from 723k to 973k, the compound translates to tetragonal with a = 0.39078 nm, c = 2.0277 nm and s.g. i4/mmm. this result is fairly in accordance with that of heat capacity. |
