Aqueous-Phase Synthesis of Crystalline Magnetite Nanoparticles by a New Mechanochemical Method

Mechanochemical Synthesis of Magnetite/Hydroxyapatite Nanocomposites for Hyperthermia

“…In the synthesis of Fe 3 O 4 /HA nanocomposites, first a suspension of superparamagnetic Fe 3 O 4 nanoparticles was prepared according to a mechanochemical method reported in elsewhere [11]. This method provides Fe 3 O 4 from ferric hydroxide (goethite) in the absence of a reducing agent; goethite is reduced to ferrous hydroxide by mechanochemical effects and the solid phase reaction between ferrous hydroxide and goethite generates Fe 3 O 4 [16]. Subsequently, HA nanoparticles were synthesized in the suspension of Fe 3 O 4 nanoparticles in the same container by the mechanochemical method mentioned above.…”
