Barium zirconate titanate-based ceramic material with stable dielectric temperature and preparation method of barium zirconate titanate-based ceramic material
The invention discloses a barium zirconate titanate-based ceramic material with stable dielectric temperature and a preparation method of the barium zirconate titanate-based ceramic material. The barium zirconate titanate-based ceramic material comprises the following components: (Ba1-xGdx) (Ti0. 9Zr0. 1) O3 + x/2, MgO and ZnO, the preparation method comprises the following steps: firstly weighing (CH3COO) 2Ba, Gd (NO3) 3, C16H36O4Ti and Zr (NO3) 4.5 H2O according to a molar ratio, preparing main crystalline phase nano-powder by a sol-gel method, then grinding the main crystalline phase nano-powder, MgO and ZnO, carrying out compression molding to prepare a flaky blank, and finally sintering to obtain the barium zirconate titanate-based ceramic material. Through the synergistic effect of the composite perovskite structure nano principal crystalline phase and the modifier, the ceramic material has the characteristics of high dielectric constant and low dielectric loss, and the dielectric constant temperature change rate is less than +/-15% due to the induction of dispersed phase change.
本发明公开了一种介电温度稳定的锆钛酸钡基瓷料及其制备方法，其组分包括(Ba1‑xGdx)(Ti0.9Zr0.1)O3+x/2、MgO及ZnO；制法为首先按摩尔比称量(CH3COO)2Ba、Gd(NO3)3、C16H36O4Ti和Zr(NO3)4·5H2O，通过溶胶凝胶法制得主晶相纳米粉体，随后将主晶相粉体与MgO及ZnO经研磨、模压成型制得片状坯体，最后经烧结制得锆钛酸钡基瓷料。本发明通过复合钙钛矿结构纳米主晶相与改性剂的协同作用使瓷料不仅具有高介电常数、低介电损耗的特点，且由于弥散相变的诱发使介电常数温度变化率小于±15％。
