method including solvent-nonsovent recrystallization, sol-gel, and spray drying and supercritical fluid technique [16]. The abovementioned methods are effective at the lab scale, and the large-scale preparation of nanoscale ener-getic materials involves great difficulties. Mechanical ball milling (also known as ball milling) is a desirable choice

Nanoparticles are claimed which consist of 50-99.99% by weight of alumina and 0.01-50% by weight of metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminum chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.

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 ...

Dec 15, 2012· Nano Ball Milling 1. BALL MILLING METHOD By Aravind N. B 2. Nano materials can be defined as those materials which have structured components with size less than 100nm at least in one dimension. Nanotechnology is an advanced technology, which deals with the synthesis of nano-particles, processing of the nano materials and their applications.

The composite electrodes exhibit excellent electrochemical performance, such as 1956 mAh/g at 0.05C rate and 91% capacity retention after 150 cycles. Moreover, the spray drying method requires only 2 s for the formation of each particle and allows a production capability of ∼10 g/h even with an ultrasonic-based lab-scale equipment.

Aug 12, 2008· Aggregation and dispersion behavior of nanometer and submicrometer scale TiO 2 particles in aqueous suspension were investigated using three kinds of mechanical dispersion methods: ultrasonic irradiation, milling with 5‐mm‐diameter balls, and milling with 50 μm beads. Polyacrylic acids with molecular weights ranging from 1200 to 30 000 g/mol were used as a dispersant, and the .

I you want, you can find more information at Langmuir 28, 11241−11249 (2012). However this is not a "cheap" method to generate nanoparticles. The cheapest way would be probably the ball milling.
