Dielectric ceramic material and preparation method thereof
The invention discloses a dielectric ceramic material and a preparation method thereof. The ceramic material is of a core-shell structure, wherein the core structure material in the core-shell structure is SrTiO3, and the shell structure material is Sr4Ti3O10. The preparation method comprises the following steps: synthesizing SrTiO3 from SrCO3 and TiO2, then partially reducing Ti<4+> in the SrTiO3 into Ti<3+> in a high-temperature reducing atmosphere, mixing the reduced SrTiO3 with Sr(NO3)2, and forming R-P phase Sr4Ti3O1o on the surface through a reaction to prepare the SrTiO3-Sr4Ti3O10 core-shell structure material. According to the invention, the material is low in price, and the dielectric constant of the prepared dielectric is 10000; and the preparation process is simple, the operability is high, and the dielectric material provided by the invention can be widely applied to various capacitors.
本发明公开了一种介电陶瓷材料及其制备方法，所述陶瓷材料为核壳结构，所述核壳结构中的核结构材料为SrTiO3，壳结构材料为Sr4Ti3O10。所述制备方法如下，通过SrCO3和TiO2合成为SrTiO3，然后在高温还原气氛下使SrTiO3中的Ti4+部分还原为Ti3+，将还原后的SrTiO3与Sr(NO3)2混合，通过反应在表面形成R‑P相的Sr4Ti3O1o，制备成SrTiO3‑Sr4Ti3O10核壳结构材料。本发明材料价格便宜，制得的电介质的介电常数为10000。本发明制备工艺简单、可操作性强，本发明提供的电介质材料可广泛应用于各类电容器中。
