Barium Ferrite Nanopowder (BaFe12O19, 99.9%, 60nm)

Barium Ferrite Nanopowder

Barium ferrite nanopowder refers to nanoscale particles of barium ferrite, a ceramic compound composed of barium (Ba) and iron (Fe). The nanopowder form of barium ferrite is produced by reducing the particle size to the nanometer scale, typically below 100 nm. This results in a significant increase in surface area, reactivity, and the potential for enhanced properties compared to bulk materials.
