Abstract
A chemical precipitation method is utilized to synthesize bismuth-strontium-calcium-copper oxide powder. Tetra-methyl ammonium hydroxide and tetra-methyl ammonium carbonate are used as a precipitant and for pH adjustment. Effect of processing parameters like carbonization time, and cation solution concentration on Bi2Sr2CaCu2O8 (Bi-2212) powders is reported. Powders with different particle size and distribution are used to fabricate Ag sheathed multifilamentary Bi-2212 round wires with diameter about 0.06 cm (corresponding to filament diameter about 3 μm). Significant sausaging was observed for wires processed with larger particle size powders. Good filament uniformity was observed for wires produced from finer powders.
