摘要

Flash sintering method was adopted to sinter SiO₂-coated BaTiO₃ ceramics to lower sintering temperature and shorten sintering time. The microstructure and dielectric property of BaTiO₃ with different amount of SiO₂ coating were studied. Samples can be flash sintered at furnace temperatures lower than conventional sintering temperature. Though the onset flash sintering temperature increased obviously with increasing SiO₂ content, the estimated sample temperatures were found close to each other. Samples with improved density was achieved with higher SiO₂ content, but their dielectric constant decreased. Flash sintered samples with 1.5 wt% SiO₂ addition possess a fair dielectric constant with improved density.
