摘　　要：研制的陶瓷材料可在超低温度(1030℃±15℃)下烧结,获得瓷料的相对介电常数高于2100,介质损耗不高于1.5%,温度特性满足X7R特性要求标准。与传统的X7R特性材料比较,本材料烧结温度更低,同时材料中不添加Pb、Hg、Cd、Cr等有害元素,符合绿色环保要求及欧盟RoHS指令要求。With the development of ceramic materials in the ultra - low - temperature sintering （1 030℃±15℃） ,the dielectric constant of ceramic materials is higher than 2 100, dielectric loss is less than 1.5%, X7R temperature characteristics meet the requirements of the standard. Compare with traditional X7 R materials, the material is lower temperature sintering material, needn＇t add Pb, Hg, Cd, Cr, and other harmful elements, is up to EU Rolls Directive requirements and green.
