摘要:
    利用简单的液相合成方法，在室温条件下制备了KCoF3粉末状产物。通过X射线粉末衍射（XRD）和扫描电镜（SEM）对其物相结构和形貌进行了表征，结果表明：KCoF3是一种ABC3型的钙钛矿结构，属于立方晶系，空间群为pm3m［221］。利用Rietveld粉末衍射峰形拟合方法对化合物KCoF3的X射线粉末衍射数据进行分析，并对其结构进行精修，表明其晶格常数为a=4.076(2)，晶胞体积为67.727(7)3，每个单胞含1个化学式（Z=1），计算密度为Dc=3.812(1) g/cm3。而对KCoF3电学性能的研究表明，在273 K附近存在Co原子自旋态的改变，高自旋态向低自旋态的变化影响了Co原子间的超交换作用，进而影响了电输运行为。
