The most common shape factor is the aspect ratio, a function of the largest diameter and the smallest diameter orthogonal to it: The normalized aspect ratio varies from approaching zero for a very elongated particle, such as a grain in a cold-worked metal, to near unity for an equiaxed grain. The reciprocal of the right side of the above equation is also used, such that the AR varies from one to approaching infinity. WebCrystal Size At very small crystal sizes, usually below about 20nm, iron oxide nanoparticles [magnetite (Fe3O4), maghemite (γ-Fe2O3), or nonstoichiometric magnetite], oxygen ions form a cubic close-packed (ccp) lattice, with smaller iron cations located at the interstices between the larger oxygen anions.
