摘要:
钛酸钡是具备高介电常数、低损耗的铁电材料,十三钛酸钡是具有低介电常数、高品质因子的微波介电材料,目前为止鲜有利用水热法合成单相十三钛酸钡的相关研究报道. 以一水合氢氧化钡和四氯化钛为反应原料,通过控制钡/钛摩尔比,利用水热法制备得到了钛酸钡和十三钛酸钡,研究了钡/钛摩尔比对反应产物的影响. 采用X射线粉末衍射仪检测所得产物的相成分,利用扫描电子显微镜观察利用水热法制备得到的十三钛酸钡的形貌. 结果表明,当钡/钛摩尔比为1∶1时,水热反应产物为钛酸钡. 当钡/钛摩尔比为1∶4时,水热反应产物为非晶相,经过晶化热处理后得到十三钛酸钡. 且所制备得到的十三钛酸钡为不规则块状,粒径大小在0.3 μm到1 μm之间,有一定的团聚现象.
Abstract:
Barium titanate is a lead-free ferroelectric material which has high dielectric constant and low dielectric loss. Barium 13-titanate is a kind of microwave dielectric material which has low dielectric constant and high-quality factor. So far, there are few literature reports on preparation of single-phase barium 13-titanate by hydrothermal method. In this paper, the barium titanate and Barium 13-titanate were synthesized by hydrothermal method, using barium monohydrate and titanium tetrachloride as raw materials. The influence of Ba/Ti molar ratio on the reaction product was studied. The specimens were characterized by powder X-ray diffraction. The morphology of Barium 13-titanate was characterized by scanning electron microscopy. Barium titanate is obtained when the Ba/Ti molar ratio is 1∶1. The hydrothermal product is amorphous phase, which turns to crystalline Barium 13-titanate after crystallized by post heat treatment, when the Ba/Ti molar ratio is 1∶4. The scanning electron microscopy image of the obtained barium 13-titanate shows that the particles are in shapes of irregularity and sizes of 0.3-1 μm, with some agglomeration.
