摘要：

We have determined the peritectic decomposition temperatures for YBa2Cu3O7-x, EuBa2Cu3O7-x and HoBa2Cu3O7-x: they are 1030, 1060 and 980 °C respectively at P = 1 atm O2. We have also determined the pressure-temperature behaviour of the orthorhombic-tetragonal transition in HoBa2Cu3O7-x. Evidence of the possibility of improving the texture of these samples by partial melting and treatment in thermal gradient is also pointed out. © 1990.
