Microwave Assisted Reflux Synthesis and Characterization of Magnetic Fe₃O₄ Micro Bubbles Embed in Nano Particles

Abstract:

Magnetic Fe₃O₄ nanobubbles surrounded by nanoparticles are prepared by adopting microwave assisted reflux method. The nanomagnetic particles surrounded by small beads like particles are fabricated by irradiating the prepaperd sample solutions by microwave radiations coupled with reflux method simultaneously at 90°C for 45 mins. The characterization of the prepared Fe₃O₄ particles are carried out by using x ray diffraction, scanning electron microscopy and transmission electron microscopy. The instrumentations shows the morphology that is thick walled bubble like with approximate diameter of about 300 nm to 400 nm surrounded by small nanoparticles of 5 nm to 30 nm in range. The particles are bubbles like and some broken bubbles showed that these might be hollow from inside.
