Temperature-stable tungstate microwave dielectric ceramic capable of being sintered at low temperature
The invention provides temperature-stable tungstate microwave dielectric ceramic capable of being sintered at low temperature, and a preparation method thereof. The ceramic comprises the following components: (1-x)Li2Mg2W2O9+xCaTiO3, wherein x is more than or equal to 2% and less than or equal to 10%, and x is mole percent. The ceramic can be sintered at the temperature of 950DEG C below, and meet the cofiring requirement of low-cost silver electrodes, and has microwave performance; the dielectric constant reaches 15-24, Qf value is high (60000-78000GHz), the temperature coefficient of resonance frequency is small, and the ceramic can be used for manufacturing a low-temperature cofired ceramic system, a multilayer media dielectric resonator, a filter and other microwave devices, and has important industrial application values.
