采用溶液法中的KCl助熔剂法制备了（11n）取向的Bi 2Sr 2CaCu 2 O 8+ x（Bi 2212）薄膜。采用NdGaO 3（NGO）的（100）衬底.采用四种不同的温度曲线进行热处理。在θ-2θ衍射图中只出现（11 n）峰。由SEM图像可知，生长出了细长的板状的Bi 2212的晶粒。从晶格匹配的观点来看，该拉长的晶粒被认为是（010）（或（100））取向的晶粒。
We have prepared (11n) oriented Bi 2 Sr 2 CaCu 2 O 8+ x (Bi2212) thin films by KCl flux method which is one kind of solution method. The (100) substrate of NdGaO 3 (NGO) was used. Heat treatment was performed with four different temperature profiles. Only the (11n) peak appeared in the θ-2θ X-ray diffraction pattern. From the SEM image, it was found that elongated plate-like crystal grains of Bi2212 were grown. From the viewpoint of lattice matching, this elongated crystal grain is considered to be (010)(or (100)) oriented crystal grains.
