通过测定Ｚｒ－４合金和Ｚｒ（Ｆｅ，Ｃｒ）２：合金在各种电解液中的阳极极化行为，和对阳极产物的电子显微镜和Ｘ射线衍射分析，得到了一种适合分离Ｚｒ－４合金中第二相Ｚｒ（Ｆｅ，Ｃｒ）２的电解液：乙醇：正丁醇：高氯酸＝２５：３：２；室温条件下，控制电位为－０．４５￣－０．８０Ｖ（ＳＣＥ）．
Anodic polarization behavior of Zr-4 alloy and Zr (Fe, Cr) 2: alloy in various electrolytes was determined and electron microscopy and X-ray diffraction analysis of the anode product were carried out to obtain a suitable Zr- The electrolyte of second phase Zr (Fe, Cr) 2 in alloy is ethanol: n-butanol: perchlorate = 25: 3: 2. The control potential is -0.45 ~ -80V (SCE ).
