摘　　要：Kroll工艺是当今钛工业生产海绵钛的主要方法,但由于存在成本高及产生有毒物质等不足,于是以FFC剑桥工艺为代表的二氧化钛直接熔盐电解方法正逐步得到重视,本文通过对克劳尔法和FFC剑桥工艺两种工艺原理进行分析比较和探述,认为FFC剑桥工艺将是最有希望替代传统Kroll工艺成为生产海绵钛的最佳方法。The Kroll process was the main method of titanium sponge production in titanium industry today. Because it had some deficiency at high cost and producing toxic substances. The method which titanium dioxide was electrolyzed directly in molten salt such as FFC, was gradually placed great importance on. The principle of Kroll and FFC process was compared. It was suggested that the FFC Cambridge＇s process had the potential to replace the conventional Kroll process.
