The effect of processing parameters on property of Bi(2223) current lead

The Bi(2223) current leads were fabricated by C.I.P. method (Cold-isostatic-pressing). The purpose of this paper is to analyze the effect of processing parameters on the critical current density. The materials of Bi(2223) current leads have been investigated by X-ray diffraction and SEM in order to study the phase structure and morphology. The maximum value of critical transport current density for bar current leads reached as high as 480A/cm(2) at 77K.
