Embodiment 1
[0030] A method for preparing a dielectric resonator with a highly water-repellent dielectric slurry, the method comprising the following steps:
[0031] Preparation of glass powder: Precisely mix 700g of calcium carbonate 75%, silicon dioxide 15%, alumina 4%, and boric acid 6% in the corundum tank according to the mass percentage, then seal the corundum tank and place it on an eight-roller ball mill. Mix the materials for 1 hour; after the mixing is completed, put the obtained mixture into a quartz crucible, place it in a 1450°C resistance furnace for heat preservation and melting for 1 hour, and obtain glass slag after water quenching of the obtained glass solution, and put the glass slag into a zirconia ball mill jar, And add pure water according to the mass ratio of material to water of 1: 1, put it on an eight-roller ball mill and grind it until the particle size D50≤1.0μm, then pour it out, and use a 600-mesh sieve to sieve, and put the sieved liquid into the oven Dry at...
