Bulk Metal Particle-Superconducting Ceramic Composite

该项目涉及到块体高T_c(77K)超导金属氧化物复合材料的制备，该材料可以制成片材、带材和可能的线材。这种材料将是由微小的金属颗粒随机分布在一系列超导氧化物上的随机复合材料。这项研究的具体目的是开发一种复合材料，它保留了超导相理想的电磁性能(例如，零电阻、高超导转变温度(Tc77K)和磁屏蔽)，但其机械性能得到了改进，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.
