Abstract：

Effects　of　ZnO–B2O3　(ZB)　addition　on　the　densification,　phase　evolution　and　microwaves　dielectric　properties　of　Ba4Sm9.33Ti18O54　(BST)　ceramics　for　low-temperature　fired　applications　have　been　investigated.　The　sintering　temperature　of　BST　ceramics　can　be　effectively　lowered　to　about　1000°C　with　introduction　of　ZB.　Tungsten　bronze　like　single　phase　is　observed　in　the　BST　ceramics　with　0.5　and　1.0%　ZB.　However,　Sm2Ti2O7　secondary　phase　appears　when　ZB　addition　reaches　2%,　and　Sm2Ti2O7　phase　gradually　increases　with　the　increase　ZB　addition.　Microwave　dielectric　properties　of　the　present　ceramics　are　strongly　dependent　on　phase　constitution　and　density.　Optimal　microwave　dielectric　properties　of　ε　=　63.4,　Qf　=　2830　GHz,　τf　=–8.8　ppm/°C　is　obtained　for　BST　ceramics　with　1%　ZB　addition.　©　2016,　Pleiades　Publishing,　Ltd.
