Abstract
Tracer diffusion of 110Ag in YBa2Cu3O7−δ has been measured in the temperature range 800–950 °C using serial sectioning. The polycrystalline samples were made either from a powder containing about 0.2% Zr prepared by a conventional technique, or from a purer powder that had been calcined in low‐pressure oxygen. Concentration profiles indicate both a volume and a fast diffusivity path contribution to diffusion. The activation energies were 227±3 and 249±17 kJ/mole for samples made from powder calcined in low‐pressure oxygen and conventional powder, respectively. Diffusion was slower in the samples made from the purer powder.This publication has 16 references indexed in Scilit:
