Electrical conductivity in nanostructured magnetite

Mar 01, 2005· Mechanical milling of Fe 3 O 4 powders for few hours produced nanometre-sized particles which exhibited a transition from cubic magnetite (Fe 3 O 4) phase to hexagonal hematite (α-Fe 2 O 3) phase.By extending the milling time to 10 h, a 95% transformation to the hematite phase could be achieved. These phases were characterized both by X-ray diffraction as well as by transmission

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a complete solid solution at temperatures above
