| Abstract: | A simlpe and convenient method of determining the content of oxygen andCu(III)in YBa_2Cu_3O_x bulk is proposed. It is based on measuring the volume ofoxygen liberated from the sample dissolved with acid. The result is compared withthat obtained from thermogravimetric analysis method and the systematic erroris estimated. The error is less than 3%. |
