本文研究了影响自燃烧工艺的几个工艺条件，如溶液ＰＨ值、溶液中水含量、加热温度等因素对凝胶化的影响；利用差热热重分析仪和Ｘ射线衍射仪分析了干凝胶的热历程及产物的物相结构．结果表明，自燃烧粉末的晶化峰温为 ５０９℃，在 ８００℃ 煅烧２ｈ即可得到晶化的一次颗粒＜５０ｎｍ的ＢａＮｄ２Ｔｉ５Ｏ１４粉末，并分析了产生温度差异的原因。
Some factors that affect the behavior of sol-gel process, such as pH value, H2O concentration and heating temperature were investigated. TG-DTAand XRD analysised the procedure of dried gels with increasing temperature and the structure of as-calcined powders. The results indicated that the crystallizing temperature of BaNd2Ti5O14 was 509℃ and the size of the crystallized powders calcined at 800℃ for 2h was 50nm.
