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.
