✦ Synopsis


This method is based on the oxidation of a known amount of iron(B) ions with oxide superconductors YElaCuO and BiSrCaCuO in a 2-5 mol 1-l solution of hydrobromic acid. The unreacted iron(B) ions were determined by cerimetric titration with ferroin as the indicator. This procedure allows the dissolution of samples even at elevated temperature. The reliability interval is 5%.

The oxygen in-diffusion process in the oxygen-deficient single 2223 phase BiLrPbo.4Sr2Ca2Cu~O~ ceramic oxide has been investigated by in situ resistance measurements during ramp annealing and isothermal annealing in flowing oxygen. It is observed that the oxygen in-diffusion is much faster than the
