No full textSeveral nanometer-scale oxide inclusions were added to Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} 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. Al{sub 2}O{sub 3} additions exhibited the most promise for forming stable pinning centers, ZrO{sub 2} and SnO{sub 2} additions were moderately promising, TiO{sub 2}, Fe{sub 2}O{sub 3}, and ZnO additions were less promising, and Y{sub 2}O{sub 3} additions destroyed superconductivity
