Effect of Size Fractionation on Purity, Thermal Stability and Electrical Properties of Natural Hematite

The present study describes the variation of grain size of natural hematite (α-Fe 2 O 3 ) from bulk to nano-scale, owing to fractionation by ball milling and also the change in vital electrical properties of the products with respect to their bulk counterpart. Hematite, an important iron ore, is pre...
