Abstract
the course of investigating synthesis routes, stability information wa s developed for YBa2Cu3O7-x, Y2Ba4Cu7O15-x, and YBa2Cu4O8. The results were obtained between similar to 900 and 1040 degrees C and involve o xygen pressures between 10 and 145 atm. The observations show that the P-o2-T ranges for stability of the three phases overlap and that some stable mixtures of the phases can be synthesized. The results are com pared to the results of other experimental studies and to calculations based on calorimetric data.
