Chemical properties of magnetite ore

  • Properties of magnetite nanoparticles synthesized through ...

    However, the magnetic properties of magnetite based nanoparticles or films highly depend upon the synthesis procedure [ 6]. Here we report a novel and simple chemical route to produce magnetite (Fe3O4) nanoparticles in a size range of 5 nm to 100 nm without calcination at high temperatures. Size effect studies conducted on these
