    • Abstract

       

      A comparative study of the methods for oxygen stoichiometry—direct inert gas fusion method and two indirect iodometric methods—has been carried out. The indirect iodometric method in which Cu(III) is directly estimated, has been found to be more precise. Several samples of YBa2Cu3Ox of varyingx, their fluorine-substituted counterparts and also Bi2Sr2Ca1Cu2Ox and Tl2Ba2Ca1Cu2Ox have been analysed.
