Abstract

The invention relates to a high water-repellent medium slurry for a dielectric resonator and a preparation method thereof. The glass powder used in the medium slurry is made of Ca-Si-B-Al series glass powder after aging treatment at 100-200 DEG C for 10-15 hours Obtained; ethylene-vinyl acetate copolymer (EVA) prepared by adding ethylene, vinyl acetate, azobisisobutyronitrile, betaine and other substances in the slurry preparation process; adding titanium dioxide, chromium trioxide, cadmium trioxide, etc. As an oxide additive to further enhance slurry stability. The medium slurry prepared by this method has high water resistance, can improve the state of the sintered film, and has a higher solid content after sintering. The application range is wider and the applicability is stronger. The medium slurry is used in the field of microwave sources, which greatly reduces its use limitations, and has obvious economic benefits while expanding the application range.

Description

technical field [0001] The invention relates to the technical field of dielectric slurry, in particular to a highly waterproof dielectric slurry for a dielectric resonator and a preparation method thereof. Background technique [0002] Dielectric resonator is a new type of resonator developed in recent years. It is a kind of resonator made of low loss and high dielectric constant material. It is small in size, light in weight, high in inherent quality factor, simple in structure, It is widely used in microwave source design due to its cheap price and other advantages. [0003] Due to the structural characteristics of the dielectric resonator, it can be easily coupled with the microstrip circuit to form a miniaturized, low-noise, high-stability, high-reliability, and low-cost microwave source, so it is very popular among users. Now it has been widely used in ground microwave communication, sea and air microwave communication, satellite communication and military high-tech fi...
