Abstract:

In order to identify the electric charge carrier in an ion-conductive calcium sulfide, tracer diffusion coefficients of sulfur have been measured by IMA (Ion Micro-Analyzer). Stable isotope 34S diffused by a gas-solid reaction was analyzed in depth by continuous sputtering of the sample. The tracer diffusion coefficient determined from the in-depth profile of 34S was expressed for a temperature range from 1053 to 1483 K by;
