【摘要】 从Ba(CH3COO)2-Cd(NO3)2-Ti(OC4H9)-H2O-CH3COOH-CH3CH2OH体系,采用溶液-溶胶-凝胶法研究多层陶瓷电容器用(Ba1-xCdX)TiO3(x=0.05)(BCT)超细粉体的制备,利用热重差热分析仪(TG-DSC)研究BCT前驱体干凝胶加热过程中各阶段的反应历程,借助X射线衍射(XRD)、比表面积测定仪研究了热处理温度对BCT粉体的物相组成、晶2粒尺寸、比表面积等的影响。得到晶相单一、颗粒尺寸在35~40nm左右、比表面积为12.9m2/g的BCT超细粉体。更多还原

【Abstract】 Cadmium and barium titanate superfine powder used for m ultilayer ceramic capacitor was prepared from Ba（CH₃COO）₂-Cd（NO₃）₂-Ti（ OC₄H₉）-H₂O-CH₃COOH-CH₃CH₂OH system by sol-gel method.The process of （Ba 1-xCd_X）TiO₃（x=0.05）（BCT） powder forming was studied by means of TG-DSC.The influence of treating temperature on the material phase ,particle size ,specific susface area were investigated by means of XRD and spe cific surface area instrument .The BCT superfine powder has been obtained ,which the powder size is 35⁴0nm,specific surface area is 12.9 m2/g,crystal phase i s single.更多还原
