The effect of step heat treatment in the critical current density of BSCCO 2223 tapes
BSCCO 2223선재의 임계전류밀도에 영향을 미치는 단계별 열처리의 효과
Abstract
The sintering process of BSCCO 2223 tapes is a complex process that is very sensitive to parameters, such as temperature, oxygen partial pressure, heating and cooling rate and holding time. During the first heat treatment, 2212 phase of precursor powder is partially transformed into 2223 phase and some residual secondary phases, such as
