Bulk Metal Particle-Superconducting Ceramic Composite

该项目涉及制造大块高Tc （77K）超导金属氧化物复合材料，该材料可以形成片状，带状和可能的导线。这种材料将是随机复合材料，由随机分散在超导氧化物上的小金属颗粒组成。该研究的具体目标是开发一种复合材料，该复合材料保留了超导相的理想电学和磁学性能（例如，零电阻，高超导转变温度（Tc 77K）和磁筛选），但其机械性能被修改以提高强度和韧性。

This project deals with the fabrication of bulk high Tc ( 77K) superconducting metal oxide composite material that could be formed into sheets, ribbons, and possible wires. The materials would be random composites consisting of small metal particles randomly dispersed throughout a host of superconducting oxide. The specific aim of the research is to develop a composite that retains the desirable electrical and magnetic properties of the superconducting phase (e.g., zero electrical resistance, a high superconducting transition temperature (Tc 77K) and magnetic screening) but whose mechanical properties are modified to improve strength and toughness.
