摘要：

Phase relations at 850-degrees-C and 870-degrees-C, and melting transitions in air, oxygen, and helium have been studied for Bi2.1Sr1.9CuO6 and for the series Bi2Sr2Can-1CunO2n+4 for n = 1, 2, 3, 4, 5 and infinity ("CaCuO2"). Up to 870-degrees-C, the n = 2 composition resides in the compatibility tetrahedron bounded by Bi2+x(Sr, Ca)3-yCu2O8, (Sr, Ca)14Cu24O41, Ca2CuO3, and a Bi-Sr-Ca-O phase. The n greater-than-or-equal-to 3 compositions reside in the compatibility tetrahedron Bi2+x(Sr, Ca)3-yCu2O8-(Sr, Ca)14Cu24O41-Ca2CuO3-CuO up to 850-degrees-C. However, Bi2+x(Sr, Ca)4-yCu3O10 forms for n greater-than-or-equal-to 3 after extended heating at 870-degrees-C. Bi2+xSr2-yCuO6 (i.e. the Ca-free, very low-T(c) phase) melts in air at 914-degrees-C, while the Bi2+x(Sr, Ca)3-yCu2O8 composition that coexists with (Sr, Ca)14Cu24O41, Ca2CuO3, and CuO melts at 895-degrees-C. During melting, all of the compositions studied lose 1-2% by weight of oxygen from the reduction of copper.
