研究了２Ｆ４特性瓷料中加入少量ＳｒＴｉＯ３及ＳｒＴｉＯ３的加入方式对材料介电性能和窑业性能的影响．试验表明，在以ＢａＴｉＯ３－ＣａＳｎＯ３为主的２Ｆ４特性瓷料中加入少量的ＳｒＴｉＯ３有明显的改性作用．ＳｒＴｉＯ３的加入使瓷料居里峰展宽、负温度特性变好、介质损耗降低，耐电强度提高．ＳｒＴｉＯ３加入方式明显影响烧结性能．先将ＢａＣＯ３、Ｓｒ－ＣＯ３、ＴｉＯ２共同合成（Ｂａ１－ＸＳｒＸ）ＴｉＯ３固溶体再进行配料烧结的比用ＢａＴｉＯ３、ＳｒＴｉＯ３进行配料烧结的有较宽的烧成范围和较好的耐潮性． The effects of adding a small amount of SrTiO3 and SrTiO3 on the dielectric property and kiln properties of 2F4 porcelain were studied. Experiments show that adding BaTiO3-CaSnO3-based porcelain with a small amount of 2T4 has a significant modification of SrTiO3. The addition of SrTiO3 broadens the Curie peak of porcelain, the negative temperature characteristics become better, the dielectric loss decreases and the electric strength increases. The addition of SrTiO3 significantly affects the sintering performance. Compared with BaTiO3, SrTiO3, BaTiO3 and SrTiO3 have better broadening range and better resistance to moisture than BaTiO3, SrTiO3 and BaCO3, Sr-CO3 and TiO2.
