Strontium titanate-based giant dielectric ceramic material doped with simultaneous donors of Lu and Ta and preparation method of strontium titanate-based giant dielectric ceramic material
The invention relates to the technical field of electronic functional materials, and provides a SrTiO3-based giant dielectric ceramic material doped with simultaneous donors of Lu and Ta and a preparation method of the SrTiO3-based giant dielectric ceramic material. The SrTiO3-based giant dielectric ceramic material with simultaneous donor doping of Lu and Ta is obtained through a solid-phase synthesis method by utilizing simultaneous donor doping of Lu and Ta at the A (Sr) site and the B (Ti) site of SrTiO3 and combining a nitrogen sintering mode, and the ceramic material has the advantages of giant dielectric effect, small dielectric loss, good frequency and temperature stability of the dielectric constant, and good dielectric property. The requirements of miniaturization of electronic components and energy storage devices on dielectric materials are met; in addition, the dosage of the doping agents Ta2O5 and Lu2O3 is relatively small, so that the production cost can be reduced; the preparation method disclosed by the invention is simple, good in repeatability, high in yield, relatively low in cost and convenient for commercial production.
本发明涉及电子功能材料技术领域，提供了一种Lu、Ta同时施主掺杂的SrTiO3基巨介电陶瓷材料及其制备方法。本发明利用Lu和Ta分别在SrTiO3的A(Sr)位和B(Ti)位同时施主掺杂，并结合氮气烧结的方式，通过固相合成法得到了的Lu、Ta同时施主掺杂的SrTiO3基巨介电陶瓷材料，该陶瓷材料具有巨介电效应，介电损耗小，介电常数的频率、温度稳定性良好，满足电子元器件小型化和储能器件对电介质材料的需求；并且，本发明中掺杂剂Ta2O5和Lu2O3的用量较少，能降低生产成本；本发明涉及的制备方法简单，重复性好，成品率高，成本较低，便于商业化生产。
