Abstract

Abstract The 0-3 connectivity lead-free barium calcium stannate titanate (BCTS)-Portland cement (PC) composites were produced by pressing and curing techniques. The effect of BCTS ceramic content on microstructure and dielectric properties of composites were studied. Scanning electron microscope images at the interfacial zone of composites showed denser microstructure between Portland cement matrix and BCTS ceramic. The dielectric constant and dielectric loss of BCTS-Portland cement composites were also found to depend on the frequency in the range tested. The dielectric results indicate that the BCTS ceramic can improve the dielectric constant (lower dielectric loss) in composites. The dielectric constant followed the cube model.

0-3连通度无铅bcts -波特兰水泥复合材料的微观结构和介电性能

采用压制和固化技术制备了0-3连接度无铅锡钛酸钡钙(BCTS)-硅酸盐水泥(PC)复合材料。研究了BCTS陶瓷含量对复合材料微观结构和介电性能的影响。复合材料界面区的扫描电镜图像显示，硅酸盐水泥基体与BCTS陶瓷之间的微观结构更为致密。bcts -波特兰水泥复合材料的介电常数和介电损耗也与测试范围内的频率有关。电介质实验结果表明，BCTS陶瓷可以提高复合材料的介电常数(降低介电损耗)。介电常数遵循立方体模型。
