- Several nanometer-scale oxide inclusions were added to Bi₂Sr₂CaCu₂Oₓ high-temperature superconductors to determine their effectiveness in creating intragranular flux-pinning sites. Powder pellets were fabricated and heat treated by partial-melt processing. Effects of the additives on melting response, superconducting properties, and microstructural development were examined. Al₂O₃ additions exhibited the most promise for forming stable pinning centers, ZrO₂ and SnO₂ additions were moderately promising, TiO₂, Fe₂O₃, and ZnO additions were less promising, and Y₂O₃ additions destroyed superconductivity.
