Description

Thorough tenzometric study of YBaSrCu3O7-δ ceramics was carried out. Depending on oxygen pressure, at which the given ceramics was fired, oxygen content in it also changed. The maximum attained oxygen content corresponded to 7-δ=6.86 composition. It is shown that properties of high-temperature superconducting ceramics was related to copper heterovalency, in particular Cu+3/Cu+2. It is noted that some copper atoms must be stabilized in the superconductor structure in the higher (+3) oxidation degree to produce materials with higher Tc
