摘要:
为了提高边界层陶瓷电容器(GBBLC)的性能,采用非匀相共沉淀法制备了包覆有CuO的BaTiO3粉体,加入B2O3、MgO以提高样品的性能,按照普通电子陶瓷的制备工艺制得一系列样品.测试了样品的密度和体积收缩率,对样品的显微结构进行了分析,讨论了部分样品的介电常数和介质损耗特性.结果表明:样品致密性得到明显改善,最大体积收缩率超过40%,介电常数最高超过7×104,介质损耗也明显降低;CuO、B2O3具有明显的促烧作用,烧结温度可降至1 100 ℃,MgO可以提高样品的性能,使得气孔率明显减小,介电性能也
Abstract:
In order to improve the performance of boundary layer ceramic capacitors (GBBLC), BaTiO3 powder coated with CuO was prepared by heterogeneous co-precipitation method, B2O3 and MgO were added to improve the performance of the samples, and a series of samples were prepared according to the preparation process of ordinary electronic ceramics. The density and volume shrinkage of the samples were tested, the microstructure of the samples was analyzed, and the dielectric constant and dielectric loss characteristics of some samples were discussed. The results show that the compactness of the sample is significantly improved, the maximum volume shrinkage rate exceeds 40%, the dielectric constant exceeds 7×104, and the dielectric loss is also significantly reduced. CuO and B2O3 have obvious sintering effect, the sintering temperature can be reduced to 1 100 °C, MgO can improve the performance of the sample, so that the porosity is significantly reduced, and the dielectric properties are also obvious
