通过在熔盐中电还原各自的氧化物（FFC剑桥工艺）制备的立方铬和球状钛粉末的微观形貌特征与优先晶体生长机制进行了比较。分析导致理解的决定力的形成立方颗粒的铬粉由于优先生长，但在钛粉中的结节状颗粒由于中断的优先生长，特别是氧原子。
Microscopic morphological features of the cubic chromium and nodular titanium powders prepared by electroreduction of the respective oxides in molten salts (the FFC Cambridge process) are compared with the preferential crystal growth mechanism. The analysis leads to an understanding of determining forces for the formation of cubic particles in the chromium powders owing to preferential growth, but nodular particles in the titanium powder owing to interruption of the preferential growth by particularly oxygen atoms.
