Study on the Precursory Powder for Bi-2223 Tape

Abstract:

Article Preview

The Phase formation in the precursory powder, the particle size and the homogenization phase distribution have been investigated in this paper. Size of the powder particle has been reduced by a ball-milling process. The effects of the ball-milling on the characteristic of the powder have been studied by XRD. The modality and distribution of 2212, Ca2CuO3 and CuO in the powder were observed by SEM. Results show that the Ca2CuO3 particle ground was about 200nm in size. The precursory powder with the non-superconducting phases distributed uniformly in the mixture powder was obtained for Bi-2223 long tape.
