Abstract

Bi-2212 was successfully synthesized from a coprecipitation process using oxalate and triethylamine solution as precipitants. Basic chemical reactions were used to calculate for the corresponding amounts of precursors and precipitants at varying amounts of oxalate. Characterization was carried out using XRD, SEM and magnetic susceptibility measurements. XRD after sintering showed that the peaks observed belong to Bi-2212 phase with varying T_c's of 83K, 64K and 70K. SEM showed enhanced formation of platelike grains with less porosity.
