摘要：
Ba(Ti0.95Sn0.05)O-3 ceramics were prepared using BaCO3, SnO2 and TiO2 et al as crude materials, La2O3 as dopant, and their dielectric properties are investigated. The morphology analysis of sintered samples was conducted by SEM. It is found that for 0.1 wt% La2O3 doped BTS5 ceramics sintered at 1290 degrees C has the highest dielectric constant. It can also be seen that the samples sintered at 1260 degrees C have higher dielectric loss, which can result from the existence of the pore. Meanwhile, in the terms of dielectric loss, 0.1 wt% La2O3 doped BTS5 ceramics has lower value and the dielectric loss is more stable with temperature varying.
