Preparation method of dielectric ceramic material
The invention discloses a preparation method of a dielectric ceramic material, and relates to the field of ceramic materials. The preparation method comprises the steps of S1, weighing the following raw materials in percentage by weight: 38-45% of zinc oxide, 48-56% of aluminum oxide, 6-12% of titanium dioxide and 0.1-1% of manganese oxide; S2, carrying out primary treatment on the weighed powder to obtain primary powder, wherein the primary treatment process comprises primary mixing, filter pressing, drying and presintering treatment; S3, carrying out secondary treatment on the primary powder to obtain secondary powder, wherein the secondary treatment process comprises secondary mixing and granulation treatment; and S4, enabling the secondary powder to be subjected to forming treatment, and obtaining a blank, and after the blank is subjected to plastic removal treatment, sending the blank to a sintering furnace for sintering treatment, wherein the sintering temperature ranges from 1260 DEG C to 1300 DEG C, the sintering time ranges from 2 h to 4 h, and finally the dielectric ceramic material is obtained. The dielectric ceramic material disclosed by the invention has relatively high Qf, has a temperature coefficient close to 0 and is low in sintering temperature.
一种介质陶瓷材料的制备方法，涉及陶瓷材料领域。包括如下步骤：步骤S1：按照重量百分比称取原料：氧化锌38～45％、三氧化二铝48～56％、二氧化钛6～12％、氧化锰0.1～1％；步骤S2：将称取后的粉料进行一次处理后得到一次粉料，所述一次处理过程包括一次混料、压滤、烘干、预烧处理；步骤S3：将所述一次粉料进行二次处理后得到二次粉料，所述二次处理过程包括二次混料、造粒处理；步骤S4：将所述二次粉料进行成型处理得到胚件；将所述胚件进行排塑处理后，再对所述胚件送至烧结炉进行烧结处理，烧结温度为1260～1300℃，烧结时间为2～4h，最后得到介质陶瓷材料。本发明的介质陶瓷材料具有较高的Qf，并且拥有近0的温度系数，烧结温度低。
