Low-temperature sintered microwave dielectric ceramic material with high Q value and high dielectric constant and preparation method thereof
The invention discloses a microwave dielectric ceramic material with a high Q value and a high dielectric constant in the technical field of electronic information microwave ceramic materials, the chemical component of the microwave dielectric ceramic material with the high Q value and the high dielectric constant is (1-x) MgAlBSi glass-xSr2Ce2Ti5O16, and x is more than or equal to 0.1 and less than or equal to 0.9; the MgAlBSi glass is prepared from the following components: 10 to 30 mol percent of MgO, 10 to 25 mol percent of Al2O3, 35 to 45 mol percent of B2O3 and 20 to 30 mol percent of SiO2. Preferably, 20 wt% < = 1-x < = 50 wt%. In the range, when the sintering temperature is 1000 DEG C, the density is the maximum, the porosity is the minimum, and the Qf value is the highest. According to the invention, the dielectric constant of the obtained microwave dielectric ceramic material system with high Q value and high dielectric constant is 80-90.0, the quality factor is 22000-35000GHz, and the temperature coefficient of resonance frequency is 4-11.5 ppm/DEG C. While ensuring that the electrical property meets the requirements of a filter, the preparation process is simple, pollution-free and low in cost.
