摘要：

High-T(c) superconducting Bi2Sr2Ca2Cu3Oy phase (2223) was produced by a solid state reaction method. Its orthorhombic cell parameters were determined by X-ray diffraction. A series of superconductor/polymer composites was made using 2223 phase and low density polyethylene (LDPE). Complex impedance measurements at room temperature were carried out. The LDPE crystallized fraction is analyzed by X-ray diffraction: it is found to increase in size with the BSCCO volume fraction. Both sintered and composite materials were subjected to electrical and magnetic examination at low temperature. The Meissner effects associated with the 110 K superconducting transition were found to be roughly preserved in the composites. The levitation force was measured. The role of grinding is discussed.
