PROCESS OF PREPARING LOW- TEMPERATURE SINTERED MICROWAVE DIELECTRIC CERAMICS

摘要

The present invention is based on a complex of bismuth, niobium oxide (BiNbO _4), or zinc, niobium oxide (Zn ₃ Nb ₂ O ₈₎ of a precursor powder solution and allowed to react for relates to a method for producing a microwave dielectric ceramic composition for a low-temperature co-fired, microwave dielectric ceramic manufacturing It prepared using the coprecipitation powder synthesis process, and thereto was added to 0.1-1% by weight of V ₂ O _5, and 0.2-2 wt.% of CuO as the sintering agent according to the method of the present invention for milling and sintering, high not only has the temperature coefficient of the dielectric constant and quality factor, and a stable resonant frequency, it can be manufactured in a microwave dielectric ceramic composition capable of firing at a temperature range of 700 to 750 ℃. ; The low-temperature co-fired, microwave dielectric ceramic composition, a production method, dielectric constant, the Quality factor
