Bi(Pb)SrCaCuO系玻璃晶化过程及晶体形貌的研究

摘要

The crystallization process and the crystal morphology in Bi(Pb)SrCaCuO glass wereinvestigated by DTA, XRD, GEM and EDAX. The microstruetures of 2201, 2212 and 2223phases with superconducting properties are like-plate crystals, but that of Cu2PbO4 andCa2CuO3 are the gathering grains. CaO is the substance in flocculation.
