Molten Salt Synthesis of CaCu3Ti4O12

摘要：

　　CCTO powders were prepared by using molten salt method in the NaCl-KCl system.The effects of temperature and holding time on phase compositions,particle morphology and size have been investigated by X-ray diffraction,scanning electron microscope and laser particle size analyzer.Using CaCO3,CuO and TiO2 as starting materials,CCTO compound could be synthesized at any temperature from 800℃ to 1000℃ in the NaCl-KCl system.The average particle size increased obviously with the increasing of temperature above 850 ℃.Holding time had great effect on grain size and morphology.
