摘　　要：选取MgO-SiO2-TiO2系作为研究对象,研究实验工艺及瓷料组成对系统介电性能的影响。借鉴高频低介瓷的基本组成原则,反复研究成分配比,确定了系统的最佳组成。高频下得到了性能优良的低介、低损耗、低电容量温度系数、高体积电阻率的多层陶瓷电容器用瓷料,用其制成的MLC可广泛应用于航空、航天、国防军事等尖端技术设备中。On basis of MgO-SiO_2-TiO_2 system ceramics, the following aspects have been studied, such as the system composition mechanism, fabrication process and so on. It is well known that low ε ceramics have been widely used in packaging and substrate materials. With their formation mechanism as a reference, the optimum composition of this system is determined. MgO-SiO_2-TiO_2 system is the principal ceramic system. And finally a low coefficient、low dissipation、low capacitance ratio and high volume resistivity MLC ceramics are obtained that can be widely used in aviation、spaceflight、national defence and military devices.
