Microwave dielectric ceramic preparation method and microwave dielectric ceramic
The invention provides a preparation method of microwave dielectric ceramic and the microwave dielectric ceramic. The preparation method comprises the following steps: respectively weighing main raw materials according to the chemical ratio of a target product Ba[(CoxZn1-x)1/3Nb2/3]O3, carrying out primary ball milling on the main raw materials, and enabling the particle size D90 of slurry obtained after primary ball milling to be 1.0-2.2 microns; drying, grinding and sieving the slurry subjected to the first ball milling to obtain dry powder; calcining the dry powder, and carrying out secondary ball milling on the calcined dry powder to obtain slurry with the particle size D90 of 1.0-1.1 microns; drying, granulating, sieving and tabletting the slurry subjected to secondary ball milling toobtain a green body; and removing glue from the green body, sintering the green body after glue removal at 1350-1500 DEG C, and annealing the green body at 1300-1350 DEG C to obtain the barium-cobalt-zinc-niobium-based microwave dielectric ceramic. According to the invention, the volatilization of raw materials is reduced, and the consistency of product performance is improved.
本发明所提供的一种微波介质陶瓷制备方法及微波介质陶瓷，包括：按照目标产物Ba[(CoxZn1‑x)1/3Nb2/3]O3的化学配比，分别称取主原料，将主原料进行第一次球磨，第一次球磨后浆料D90粒径为1.0～2.2微米；将第一次球磨后的浆料烘干、研细并过筛，获得干粉料；煅烧干粉料，并将煅烧后的干粉料进行第二次球磨，第二次球磨后浆料D90粒径为1.0～1.1微米；将第二次球磨的浆料进行烘干、造粒、过筛及压片处理，得到坯体；将坯体进行排胶，将排胶后的坯体于1350℃～1500℃烧结，于1300℃～1350℃退火，得到钡钴锌铌基微波介质陶瓷。本发明减少了原料的挥发，并且提高了产品性能的一致性。
