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.
