摘要/Abstract

摘要：以四甲基氢氧化铵为矿化剂，通过水热合成方法制备出钛酸钡纳米粒子.分别讨论了钡源、钡离子浓度、反应前驱体pH值以及反应时间和温度对钛酸钡纳米粒子大小和形状的影响.结果表明：采用四甲基氢氧化铵有机碱作为矿化剂，可以比较容易制备出呈明显单分散性分布的钛酸钡纳米粒子，而且粒子纯度高.通过改变反应条件可以合成出不同尺寸的纳米粒子.是制备单分散BaTiO3纳米粒子的一个十分有效的方法.

Abstract: Nanocrystalline barium titanates were synthesized using a hydrothermal method with tetramethyl ammonium hydroxide as the mineralizer.The effects of the sources of barium,concentration of Ba2+ ions,pH of precursor solutions,reaction time and temperature on the formation of BaTiO3 nanoparticles were investigated.It was shown that monodispersed monolithic BaTiO3 nanoparticles and purer samples could be prepared pretty easily with the application of the organic base of tetramethyl ammonium hydroxide.Monolithic BaTiO3 nanoparticles of various sizes could be synthesized by the adjustment of reaction conditions.

Key words: barium titanates nanoparticle, hydrothermal method, organic base
