Abstract
⺠From report protocols, chemical synthesis of magnetite with FeCl3 (stable in air) instead of FeCl2 or Fe(NO3)3, precursor. ⺠Chemical reduction with Na2SO3 provides an additional advantage. ⺠As any eventual reformation of Fe3+ from reoxidization of produced Fe2+ may be sequestered by remaining SO32â in the medium. ⺠Nanoparticles are stably individualized with tetramethylammonium hydroxide that acts as a surface-active agent. ⺠Thermal treatment reduces further the mean sizes of particles, as required for many medical uses.
