Ball milling method and spray drying method of systhesizing oxide nanopaticels

particles are prepared by a coprecipitation method, and a horizontal tumbling ball mill is used to mechanochemically synthesize submicron-sized HAp particles. According to Iwasaki et al9 this process promotes the dispersion of Fe 3 O 4 nanoparticles in the HAp matrix. The magnetic Fe 3 O 4 particles are coated with HAp by spray-drying. Donadel
