Ys. Sung et Ee. Hellstrom, A STUDY OF REACTIONS AMONGST (BI,PB)(2)SR2CACU2OX AND PHASES ON THE LINE BETWEEN CAO AND CUO TO FORM (BI,PB)(2)SR2CA2CU3OX, Physica. C, Superconductivity, 252(1-2), 1995, pp. 155-159
Reactions amongst (Bi,Pb)(2)Sr2CaCu2Ox and combinations of phases on t
he line between CaO and CuO were studied. (Sr,Ca)(2)CuO3 and CuO forme
d in phase assemblages that initially contained CaCuO2, or CaO plus Cu
O, or Ca2CuO3 plus CuO. The results showed that the phase assemblage c
omposed of (Bi,Pb)2Sr2CaCu2Ox, Ca2CuOx, and CuO was the best of those
studied to form (Bi,Pb)(2)Sr2Ca2Cu3Ox.
