Effect of HIPing on conductivity and impedance measurements of DyBi5Fe2Ti3O18 ceramics

[摘要] X-ray diffraction, a.c. impedance and conductivity (a.c. and d.c.) have been used to characterize DyBi₅Fe₂Ti₃O₁₈. Samples were prepared by solid state double sintering method. A few samples were also subjected to hot isostatic pressing (HIP) at 800°C for 2 h at 100 MPa pressure. The data on XRD, impedance and conductivity of two sets of samples are compared to understand study of effect of HIPing on the properties of DyBi₅Fe₂Ti₃O₁₈.
