Ossila M2440B1 is iron (III) oxide nanopowder in the γ-Fe2O3 phase, also known as maghemite (CAS 1309-37-1). It is supplied as a dark orange/brown powder of spherical particles with an average size of 18 nm and a purity above 99.55%, making it suited to battery and electrode research.
Maghemite has a cubic crystal structure and is ferromagnetic at room temperature, a property that led to its early use in recording tapes. Iron oxide more broadly is used in pigments, catalysts and thermite.
In energy storage work, γ-Fe2O3 nanoparticles have been combined with graphene to build Li-ion battery anodes. These composites have shown a reversible capacity of 711 mAh/g and kept 94% of their capacity after 50 cycles, highlighting iron oxide as an abundant anode material.
- Anode material research for lithium-ion batteries.
- Fabrication of γ-Fe2O3/graphene composite anodes.
- Studies of ferromagnetic iron oxide nanoparticles at room temperature.
- Research involving iron oxide pigments, catalysts or thermite.
