- Abstract
The process of zinc diffusion in YBa[sub 2]Cu[sub 3]O[sub 7 - x] ceramics with a porosity of 20-30% was studied in the temperature interval from 110 to 450°C using a [sup 65]Zn radioactive tracer. The temperature dependence of the tracer diffusion coefficient is described by the relation D = 5 × 10[sup -9]exp(-0.25 eV/kT) cm²/s. It is concluded that zinc migrates predominantly via pores and intergranular layers in the ceramics.
