对非晶态Cu~+快离子导体0.4CuI-0.3Cu_2O-0.3P_2O_5在等温热处理条件下测量离子电导率的同时,进行了X射线衍射(XRD)与扫描电子显微术(SEM)研究。结果表明:初始的非晶态材料是分相的;随着等温热处理,分离的非晶第二相逐渐消失,并发生非晶态晶化;晶态的γ-CuI与Cu_2P_2O_7先后析出,逐渐长大。此材料的分相和晶化行为同电导率反常性的对应,再一次证实了非晶态快离子导体中的相界效应及其普遍意义。
X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies of 0.4CuI-0.3Cu 2 O-0.3P 2 O 5 amorphous Cu ~ + fast ionic conductor were carried out under isothermal heat treatment conditions. . The results show that the initial amorphous materials are phase-separated. With the isothermal heat treatment, the amorphous second phase gradually disappears and amorphous state occurs. The crystalline γ-CuI and Cu_2P_2O_7 precipitate successively, Gradually grow up. The phase separation and crystallization behavior of this material correspond to the conductivity anomalies, confirming once again the phase boundary effect in amorphous fast ionic conductors and their general significance.
