Abstract In this paper, the diffusion mechanism of oxygen ions in La2Zr2O7/YSZ (LZ/YSZ) composites was investigated experimentally and numerically. LZ/YSZ composite samples with multiple amounts of LZ were successfully synthesized via a two-step sintering process. The so-obtained samples preserved most of the tetragonal phase (82.2 mol%) in YSZ. Moreover, an adhesive grain boundary and good chemical compatibility between YSZ and LZ grains were verified in the composite samples. The measured… CONTINUE READING
