An “easy‐to‐handle” Fe 3 C powder constituted of nanoparticles is prepared in a simple, fast and relatively cheap way. The nanoparticles are crystalline, small ( d ≈ 8 nm), and superparamagnetic. Despite the absence of any significant coating shell, these nanoparticles are stable against oxidation and can represent a perfect base for the generation of novel ferrofluids.
