摘要：

Ceramics of composition Ba1-xLaxTiO3 were prepared by two-step sintering method. The average grain size of the sintered samples were 300nm (for x = 0.025) and 500nm (for x = 0.05). Relative densities of these samples were 92.8%TD and 92.3%TD. Despite the small grain size, the magnitude of dielectric permittivity of ceramics has higher value in comparison with coarse-grained materials sintered by standard technology (with grain size >1 mu m).
