Preparation method of micro-nano dielectric ceramic material
The invention belongs to the technical field of dielectric ceramic materials, and particularly relates to a preparation method of a micro-nano dielectric ceramic material. The method adopts two or more sizes of powder materials as raw materials, and the powder size needs to meet a close packing model. The size range of the dielectric ceramic powder is 30-500 nm, and when the diameters of the large-particle powder and the small-particle powder are DL and DS respectively, the size of the powder needs to meet the condition that DL is smaller than or equal to 0.414 DS; the mass ratio of the large-particle powder to the small-particle powder ranges from 1:1 to 20:1; and the sintering temperature is controlled to be 950-1200 DEG C, and the heat preservation time is 2-14 hours. The preparation method has the advantage of controllable preparation of the micro-nano dielectric ceramic material, does not need special sintering equipment and sintering aids, can be used for production of a new generation of micro-nano dielectric ceramic, and has very strong practicability.
本发明属于电介质陶瓷材料技术领域，尤其涉及一种微纳米电介质陶瓷材料的制备方法，所述方法是采用两种或多种尺寸的粉体材料作为原料，粉体尺寸需满足密堆积模型。介电陶瓷粉体尺寸范围在30‑500nm，当大颗粒粉体和小颗粒粉体直径分别为DL和DS时，粉体尺寸需满足DL≤0.414DS；大颗粒粉体和小颗粒粉体质量配比在1:1至20:1之间；控制烧结温度在950‑1200℃，保温时间为2‑14h。本发明具有可控制备微纳米电介质陶瓷材料的优势，且制备方法无需使用特殊的烧结设备、助烧剂，可作为新一代微纳米电介质陶瓷的生产，具有很强的实用性。
