Microwave Property of Low-Temperature-Sintered Ba1-xSrxTiO3 Ceramics with B-Li Glass Sintering Aid
Ferroelectrics, 2010Co-Authors: Haitao Jiang, Jiwei Zhai, Xiujian ChouAbstract:This paper reports on fabrication and characterization of low-temperature-sintered barium-strontium titanate (BST) ceramics with B-Li glass as sintering aid. With the addition of B-Li glass, the sintering temperature of BST can be effectively reduced from 1350 to 920°C due to the presence of a liquid phase. The effects of B-Li glass addition on phase composition, microstructure, dielectric properties, and Microwave properties of the BST ceramics were sytematically investigated. The sample (Ba0.50Sr0.50TiO3) with 5.0 wt% B-Li sintered at 920°C for 5 h exhibits optimized room temperature dielectric properties, including a moderate dielectric constant (ϵ = 1051), a low dielectric loss (0.0048) and a high tunability (31%) at dc electric field of 45 kV/cm and 10 kHz. At 1.150 GHz, it possesses a dielectric constant of 695 and Q value of 207.

structure Microwave Property relations of ca and sr titanates
Journal of The European Ceramic Society, 2001Co-Authors: P L Wise, Ian M Reaney, W E Lee, T Price, D Iddles, D S CannellAbstract:Abstract The Microwave dielectric properties of the Sr x Ca 1− x TiO 3 , Sr n +1 Ti n O 3 n +1 and (Sr x Ca 1− x ) 3 Ti 2 O 7 series have been measured. TCF decreases from +1647 to +859 MK −1 as Ca content increases in the Sr x Ca 1− x TiO 3 series, due to the onset of octahedral tilt transitions. Additions of excess SrO to SrTiO 3 form the Sr n +1 Ti n O 3 n +1 series with Q a maximum for Sr 3 Ti 2 O 7 . Ca substitutions to Sr 3 Ti 2 O 7 result in a solid solution limited to the Sr and Ca rich ends of the (Sr x Ca 1− x ) 3 Ti 2 O 7 series with Q a maximum of 10 250 at 2.5 GHz for Sr 2.4 Ca 0.6 Ti 2 O 7 and TCF a minimum + 50 MK −1 for Ca 3 Ti 2 O 7 . The variation of TCF for the (Sr x Ca 1− x ) 3 Ti 2 O 7 series was also attributed to the onset of octahedral tilt transitions.

structure Microwave Property relations in srxca 1 x n 1tino3n 1
Journal of The European Ceramic Society, 2001Co-Authors: P L Wise, Ian M Reaney, W E Lee, T Price, D Iddles, D S CannellAbstract:The Microwave dielectric properties of the (SrxCa(1−x))n+1TinO3n+1 series have been measured. When n=∞, a linear decrease in TCF from +1647 (SrTiO3) to 859 (CaTiO3) MK−1 was observed as Ca content increased. This trend in TCF was attributed to the onset of octahedral tilt transitions brought about by decreasing tolerance factor. Additions of excess SrO to SrTiO3 formed the Srn+1TinO3n+1 series with Q a maximum for Sr3Ti2O7. Ca substitutions to Sr3Ti2O7 resulted in a solid solution limited to the Sr and Ca rich ends of the (SrxCa1−x)3Ti2O7 series with Q a maximum of 10 250 at 2.5 GHz for Sr2.4Ca0.6Ti2O7 and TCF a minimum of 50 MK−1 for Ca3Ti2O7. The variation of TCF for the (SrxCa1−x)3Ti2O7 series was also attributed to the onset of octahedral tilt transitions.
