The project will deal with the processing and fabrication of superconducting ceramic materials. The main objective of the research is to prepare yttrium-barium-copper oxides in bulk, sheet, and fiber shapes. To accomplish this, both molten salts and high- quality sinterable ceramic powders of proper cation ratio will be used as starting materials. Powders will be synthesized in the laboratory from aqueous cation solutions by using homogeneous precipitation and emulsion precipitation techniques. Molten salts will be prepared from barium hydroxide, copper nitrate, and yttrium hydroxide salts. The influence of individual processing steps on the characteristics of the material synthesized and on the overall performance of the component as a superconducting device will be investigated. A significant level of cooperation with USDOE Ames Laboratory scientists will be an integral part of the program.

该项目将涉及超导陶瓷材料的加工和制造。 该研究的主要目标是制备块状、片状和纤维状的钇钡铜氧化物。 为了实现这一目标，将使用熔盐和具有适当阳离子比例的高质量可烧结陶瓷粉末作为起始材料。 粉末将在实验室中通过使用均相沉淀和乳液沉淀技术由阳离子水溶液合成。 熔盐由氢氧化钡、硝酸铜和氢氧化钇盐制备。 我们将研究各个加工步骤对合成材料特性以及超导器件组件整体性能的影响。 与美国能源部艾姆斯实验室科学家的大量合作将是该计划的一个组成部分。
