We investigated the deuterium diffusion in the dense SnO2 polycrystalline doped with ZnO. From the secondary ion mass spectrometric analysis, the deuterium diffusion was revealed to reflect the concentration of ZnO additive in SnO2. The defect responsible for diffusion was controlled, after the grain boundary segregation of Zn and secondary phase formation in SnO2.
