The formation behaviour of Bi2Sr2CaCu2Ox from compounds prepared by hydrolysis of metal alkoxides was studied and Bi2Sr2CaCu2Ox films on metal substrates were fabricated using a metal alkoxide solution. Bi2Sr2CaCu2Ox was formed through intermediate phases such as Bi2Sr2Cu1Ox, Bi2CuO4, SrCO3, CaCO3 and CuO. Bi2CuO4 was initially formed with SrCO3, CaCO3 and CuO, and then reacted with SrCO3 to form Bi2Sr2Cu1Ox
研究了由金属醇盐水解制备的化合物形成 Bi2Sr2CaCu2Ox 的行为,并使用金属醇盐溶液在金属基底上制备了 Bi2Sr2CaCu2Ox 薄膜。Bi2Sr2CaCu2Ox 是通过中间相形成的,例如 Bi2Sr2Cu1Ox、Bi2CuO4、SrCO3、CaCO3 和 CuO。Bi2CuO4 最初与 SrCO3、CaCO3 和 CuO 形成,然后与 SrCO3 反应形成 Bi2Sr2Cu1Ox。Bi2Sr2Cu1Ox 与 CaCO3 和 CuO 反应生成 Bi2Sr2CaCu2Ox。使用金属醇盐溶液以Bi∶Sr∶Ca∶Cu=2∶2∶2∶3的名义组成在镍基体上成功制备了Bi2Sr2CaCu2Ox薄膜。Bi2Sr2CaCu2Ox 在 770°C 或更高的烧成温度下在 Ni 衬底上析出,并且在 800°C 的烧成温度下获得了尖锐的 ΔTc。
