Abstract
A novel method for forming homogeneous silver high temperature superconductor (HTS) composites. The novel method comprises a chemical coprecipitation of silver, barium, yttrium, and copper salts solutions, followed by calcination and milling processes. The novel method has an advantage of retaining all the virtues immanent in a composite HTS, for example, increased critical current density (Jc), and improved mechanical properties, while bypassing extant and deficient methodologies for forming a composite, the deficient composites characterized by heterogeneity.
