use of a sintered ba - mg - w perowskites as dielectric resonator and microwave range and dielektrisches substrate in microwave range

摘要

A dielectric material for high frequency having a composition formula xBaO.yMgO.zWO7, a composition formula xSrO.yMgO.zWO7 or a composition formula xBaO. yMgO.zWO7.wTaO5/2 wherein x, y, z and w etc. have a specified relationship. It has a high inductivity and a high Q value in a high frequency region especially a microwave and a milliwave. IMAGE
