Dataset on the effect of carbon sources on the morphology and crystallite size of Fe/C composite microspheres prepared by the spray drying process

The data presented in this manuscript showed the effect of the carbon sources on the morphology and crystallite size of Fe/C composite microspheres obtained after reduction of the as spray-dried powders. Each morphology, phase, and crystalline size of powders obtained after spray-drying and subsequent heat-treatment were investigated.
