Abstract:
1. A method of making a plurality of nanoparticles, wherein the plurality of nanoparticles comprises at least one of a metal phosphate, a metal silicate, a metal oxide, a metal borate, a metal aluminate, and combinations thereof, and wherein the plurality of nanoparticles is substantially monodisperse, the method comprising the sequential steps of: a) providing a slurry of at least one metal precursor; b) maintaining the pH of the slurry at a predetermined value in a range from about 1.0 to about 3.0; c) mechanically milling the slurry; d) drying the slurry at a temperature in a range from about 100° C. to about 150° C. to form a powder; and e) calcining the powder at a predetermined temperature to form the plurality of nanoparticles, wherein said plurality of nanoparticles is substantially unagglomerated.
