Abstract

This paper provides an outline for the use of secondary ion mass spectrometry (SIMS) in the determination of diffusion data in metal oxides. The focus is on the determination of Nb bulk and grain boundary diffusion coefficients in TiO₂ and zirconia. Specifically, the diffusion of Nb in TiO₂ and yttria doped (10 mol.-%) ZrO₂ (10YSZ) has been assessed. The following bulk diffusion coefficients D_93Nb were obtained D_93Nb=(1.03±0.051) × 10^-18 m² s^-1 10YSZ(1273K) D_93Nb=(1.91±0.096) × 10^-16 m² s^-1 TiO₂(1273K) The grain boundary diffusion parameter for Nb grain boundary diffusion in 10YSZ was also determined D_93Nbδα=(7.48±0.37) × 10^-25 m² s^-1 10YSZ(1273K) The Nb grain boundary diffusion coefficient D′_93Nb was determined to be D′_93Nb=(3.99±0.20) × 10^-16 m² s^-1 10YSZ(1273K).
