To fabricate the energy storage ceramics with large sizes for pulsed power transmission line, the densification behavior and dielectric properties of Ba 0.3 Sr 0.7 TiO 3 with 0-8 mass BaO-Al 2 O 3 -B 2 O 3 -SiO 2 glass additive were investigated. With increasing glass content, both the densification temperature and densification rate decreased remarkably. The shrinkage rate mismatch caused by green density gradient also reduced remarkably, which contributed to the fabrication of large sizes of ceramic with dense microstructure. The additions of glass phase decrease the dielectric constant. However, the breakdown strength of the samples can be increased by a factor of 1.5 over the pure BST because of the modification of the microstructure. For the samples containing 4 mass glass additions, optimal dielectric properties were obtained: dielectric constant is 440, dielectric loss is 3.5×10 -3 at 1 MHz, and breakdown strength is 16.4 kV/mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
