Novel microwave dielectric ceramic capable of being sintered at low temperature and preparation method thereof
The invention discloses a novel microwave dielectric ceramic capable of being sintered at low temperature, which has the chemical composition of SrZnV2O7 and adopts SrCO3, ZnO and NH4VO3 as raw materials. The preparation method comprises the following steps: proportioning according to a stoichiometric ratio, carrying out ball milling, drying, sieving and presintering at 625 DEG C, and carrying outsecondary ball milling, drying, granulating, molding and sintering at 730-760 DEG C to obtain the microwave dielectric ceramic capable of being sintered at low temperature. The microwave dielectric ceramic provided by the invention is low in sintering temperature, has a dielectric constant of 10.96-11.78 and a quality factor of 48475-56666GHz, is simple in preparation process, and has a wide application prospect in industry.
