摘要：

We report the high temperature behaviour of single-phase YBa//2Cu//3O//9// minus //y. This compound reveals superconductivity above 90 K. We performed high temperature (20 - 960 degree C) resistivity measurements, differential thermal analysis and thermogravimetric analysis investigations. It was found that substantial oxygen depletion occurred above 420 degree C. The oxygen content changed reversibly with temperature at ambient pressure. The second-order-like transition around 650 degree C, observed by differential thermal analysis, is an orthorhombic-tetragonal rearrangement of the lattice.
