Ferox Micron ZVI and Nano ZVI High Surface Area Small

Ferox Nano is available in a form of a dry powder or a water slurry. The nanoparticles exhibit an average size of 50 nm, an average surface area of 20-25 m 2 /g and typically about 80% ZVI. The packaging of Ferox Nano allows greater flexibility in mixing and application without reactive losses which are so common in nano iron projects.
