Abstract

There are now many routes to the synthesis of YBa₂Cu₃O_7-x. The method of mixing the oxides and heating them to 950°C is one of the earliest and seems to be the crudest. Nevertheless it seems that this is still the most widespread method used. Several high-temperature and other analytical techniques were performed on the superconductor prepared from BaCO₃, Y₂O₃ and CuO. It was found that the superconductor retained significant amounts of carbonate up to temperatures above 1200°C. BaCO₃ should be heated separately to about 1400°C before mixing with the other oxides, to prepare the superconductor at 950°C.
