This project deals with a novel method of fabricating ceramic oxide-metal (silver) superconducting composite using explosive shock wave propagation technique. The advantage of this technique is that it does not involve significant heating (100oC). Mixtures of silver powder and yttrium-barium-copper-oxygen powder of different fractions will be consolidated and encapsulated in silver into bars. These will be drawn/rolled to wires and subsequently heat treated. The processed components and precursors will be examined for Meissner effect (diamagnetic response) and transition temperature. Magnetization studies and superconducting current transport studies will be made in collaboration with the Los Alamos National Laboratories.

本计画系探讨一种利用爆炸冲击波传播技术制备氧化物陶瓷-金属（银）超导复合材料的新方法。这种技术的优点是它不涉及显着的加热（100 ℃）。不同分数的银粉末和钇-钡-铜-氧粉末的混合物将被固结并封装在银中成条。这些将被拉伸/轧制成线材，随后进行热处理。将检查加工组件和前体的迈斯纳效应（抗磁响应）和转变温度。磁化研究和超导电流传输研究将与洛斯阿拉莫斯国家实验室合作进行。
