摘要： 通过KDC方法成功制备了六钛酸钾(K2Ti6O13)晶须,并进行了热重分析和差热分析,研究烧结时间和烧结温度对K2Ti6O13晶须结晶过程的影响,通过X射线衍射分析了K2Ti6O13晶须的相组成和晶体指数.此外,通过扫描电子显微镜和透射电子显微镜研究晶须的微观结构,揭示了K2Ti6O13晶须的生长机理.

关键词: K2Ti6O13晶须;KDC方法;煅烧温度;微观形貌;生长机理

Abstract: Potassium hexatitanate (K2Ti6O13) whiskers were successfully prepared by the kneading-drying-calcination(KDC) method.The influence of the sintering time and sintering temperature on the crystallization process of the K2Ti6O13 whiskers were investigated by a thermogravimetric and differential thermal analysis.The phase composition and crystal indices of the K2Ti6O13 whiskers were analyzed by X-ray diffraction.Furthermore, the microstructure of the whiskers was investigated by scanning electron microscopy and transmission electron microscopy, which revealed that the growth mechanism of the K2Ti6O13 whiskers.
