Microwave dielectric ceramic material, and preparation method and application thereof
The invention provides a microwave dielectric material used as a 5G communication device, and a preparation method and application thereof. The microwave dielectric ceramic material suitable for industrial large-scale production is designed on the basis of industrial electronic-grade raw materials; the sintering temperature of MgTiO3 ceramic is reduced through a simple method, and the good microwave dielectric property of the system is kept; the ceramic material is prepared through the steps of material proportioning, mixing, drying, presintering, ball milling, sanding, spray granulation, green body pressing, sintering and the like. The ceramic material can be used for producing a ceramic dielectric filter for a 5G communication base station antenna. Compared with the prior art, the ceramic material is completely made of industrial electronic-class raw materials; the industrial large-scale production of the ceramic material is realized through fine control of ball milling and sanding granularity and a proper primary pre-sintering temperature process, and compared with foreign similar microwave materials, the microwave dielectric material has an obvious cost advantage.
