摘要

采用醋酸钡和异丙醇钛为原料, 邻苯二酚作钛醇盐的稳定剂, 制备了BaTiO3凝胶纤维; 采用正己烷作溶剂, 将BaTiO3凝胶纤维在180℃条件下溶剂热处理12h; 对预处理过的BaTiO3纤维以1℃/min的升温速率热处理至1100℃, 得到致密的BaTiO3陶瓷纤维. 对所得的BaTiO3陶瓷纤维采用红外光谱(IR), X射线衍射(XRD)和扫描电子显微镜(SEM)等一系列手段进行表征.

Abstract

Dense BaTiO3 ceramic fibers were obtained by solvothermal treatment of the green gel fibers, which were drawn from a sol using barium acetate hydrate and catechol-complexed titanium isoproposide as starting materials, at 180℃ for 12h in n-hexane following a heat process to 1100℃ with a heating rate of 1℃/min for crystallization. The as-synthesized BaTiO3 ceramic fibers were characterized by X-ray diffraction (XRD), Infrared (IR) spectra and scanning electron microscope (SEM) techinques.

Key words： BaTiO3; ceramic fiber; sol-gel; solvothermal
