Crystalline fe
Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite. It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below. Magnetically, α-iron is paramagnetic at high temperatures. However, below its Curie temperature (… WebUniform, ultra-thin, single-crystalline Fe 3 O 4 nanowires with narrow diameter distribution centered at 15 nm and length up to several microns, were synthesized by a simple hydrothermal route with the assistance of polyethylene glycol (PEG) 400.

WebMar 1, 2003 · Apparently, the Fe o component (poorly crystalline) is more effective than Fe d at stabilizing soil aggregates, even though it is present in lower concentrations. The Fe o component appears more important than OC in terms of WSA and MWD for soils with relatively low soil organic matter contents.
