Description
Summary:Ceramics of composition ... were prepared by two-step sintering method. The average grain size of the sintered samples were 300 nm (for x = 0.025) and 500 nm (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 ...m).
