Preparation of Dense BaTiO_3 Ceramic Fiber by a Sol-Gel and Solvothermal Route

Dense BaTiO_3 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 BaTiO_3 ceramic fibers were characterized by X-ray diffraction(XRD),Infrared(IR)spectra and scanning electron microscope (SEM)techinques.
