Nanoparticles of zero-valent iron, produced by unique technology of NANO IRON, s.r.o. company, exhibit an average particles size of 50 nm, an average surface area of 20-25 m2/g, a narrow particle size distribution of 20-100 nm and a high content of iron in the range of 80-90 wt. %. 
XRD pattern of zero-valent nanoparticles of α-Fe with weight content of ≈ 90 % and average particle size of 50 nm (derived from the Scherrer formula); magnetite - Fe3O4 (m) as a by-product. 
Mössbauer spectrum of α-Fe nanoparticles (gray spectrum); the spectrum measured at room temperature, the blue lines correspond to magnetite.  
Primarily produced (non-stabilized) Fe(0) nanoparticles with recordly small size and narrow size distribution by view of scanning electron microscopy (SEM).
