摘要
Sol-gel synthesis of Ba1-xSrxTiO3 (x=0.1, 0.2) ceramic fibers with a diameter of 6-10 mum using catechol-complexed titanium isopropoxide, barium acetate hydrate and strontium acetate hydrate as precursors has been investigated. The green fibers and those sintered at different temperatures were characterized by thermogravimetry analysis (TGA), infrared spectroscopy (IR), X-ray diffraction (XRD) and scanning electron microscope (SEM) techniques. Microstructural development of barium strontium titanate (Ba1-xSrxTiO3) ceramic fibers as a function of strontium concentrations was studied. X-ray diffraction indicated that the well-developed cubic phase of (Ba, Sr)TiO3 was crystallized at 1100degreesC. (C) 2003 Elsevier B.V. All rights reserved.
