Abstract:
Optimum conditions and experimental details for the formation of v-Fe203 from
goethite have been worked out. In another method, a cheap complexing medium of starch was
employed for precipitating acicular ferrous oxalate, which on decomposition in nitrogen and
subsequent oxidation yielded acicular y-Fe203. On the basis of thermal decomposition in dry
and moist nitrogen, DTA, XRD, GC and thermodynamic arguments, the mechanism of
decomposition was elucidated. New materials obtained by doping ~'-Fe203 with 1-16 atomic
percent magnesium, cobalt, nickel and copper, were synthesised and characterized
