Abstract: Flower-like indium nanostructures with an average diameter of about 450 nm were successfully synthesized through an ultrasonic dispersion method in ployol system, and were characterized by TEM, XRD, and TG/DTA. The results indicated that these flower-like indium nanoparticles were built from nanopetals and nanorods, and possessed the same crystal structure as bulk indium. Their tribological property as additives in lubricant oil was evaluated on a four-ball tester, and tribological results showed that the as-obtained flower-like indium nanoparticles had an excellent ability in friction-reducing and antiwear.

Key words: Nanostructures, Ultrasonic, Solution dispersion, Tribological property
