Primary crystallization field and crystal growth of Bi2Sr2CaCu2Ox

[[abstract]]The primary crystallization field of Bi2Sr2CaCu2Ox was determined by differential thermal analysis, crystal-growth experiments, and X-ray analysis. The optimal composition region was: Bi-0.33+/-0.01 (Sr2/3Ca1/3)(0.43+/-0.01)Cu0.24+/-0.01Oy. Liquid-phase-epitaxy growth experiments were performed on six different compositions from this region. These experiments confirmed the primary crystallization of the 2212 phase at temperatures near 895 degrees C. The crystalline films exhibited a relatively uniform composition, and the composition was Bi2.10Sr2.00Ca0.88Cu2.03Ox.[[fileno]]2010314010006[[department]]化學
