VIEW PDF: SURFACTANT EFFECT ON THE STRUCTURAL AND MAGNETIC PROPERTIES OF Fe POWDERS PREPARED BY WET MILLING
The effect of wet milling with benzene on the structural and magnetic properties of Fe powder was investigated. Average crystallite sizes of 14 nm and 7 nm were obtained for the dry-milled and wet-milled samples respectively. It was found that benzene reacts with the Fe powder during wet milling, carbon entering into the Fe structure. After annealing, the average crystallite sizes remained at 27 nm for dry-milled Fe and 25 nm for wet-milled Fe. Some of the benzene evaporated during annealing, however, a significant amount of benzene still remained in the powder mixture after annealing.
Keywords: ball milling, surfactant, α-Fe, powders, crystal structure, microstructure.
