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
