Indium addition to the BSCCO system in the 2234 stoichiometry
Indium addition to the BSCCO system has been found to inhibit the growth of the Bi2223 phase. Resistance versus temperature and X-ray diffraction measurements indicate no substitution of indium into the crystal structure of Bi2223 but is substituted into the Sr-site of Bi2212. Volume fraction and bulk morphologies exhibit an inhibition of the inclusion of Ca/Cu units into Bi2212. X-ray Diffraction of resintered samples show a decrease in the Bi2223 phase regardless of the presence of indium.
