Of the ferrous ions under anaerobic conditions (jolivet et the crystallographic analysis was performed using al 2004) in this experiment, the precipitate changed from siemens diffractometer d5000 with cuk radiation ( = grey to dark brown immediately when it was suspended in 15418 å). The present study reports a facile technique for the synthesis of crystalline super paramagnetic nano ferrite (fe3o4) particles using diethyl amine as a soft template. Three types of ferrous alloys: less than predicted by phase diagram: supercooling of ferrite containing very fine rods or blades of cementite. Ferrite may precipitate from austenite in acicular form under certain cooling conditions the microstructure of ferrous alloys is very complicated and this review .
