Abstract

Abstract In order to determine the effective oxidation state of Cu ( p) and oxygen content ( y) with the iodometric method, a new formula for calculating p and y of high T c copper oxides is presented here. The formula of p involves a corrective term of 8 CV 1/ M 1, which reduces a systematic calculating error. With this approach, for YBCO, the value of p of YBCO is improved by 5% and y by 0.02, as compared with the conventional method.
