Abstract

A chemical precipitation method is utilized to synthesize Bi-Sr-Ca-Cu-O powder. Tetramethyl ammonium hydroxide and tetramethyl ammonium carbonate are used as a precipitant and for pH adjustment. The precursor powder is heat treated in a low pressure oxygen atmosphere. The decomposition of the precursor was studied by using TGA and DTA techniques. The powders were characterized by using XRD and SEM.
