Abstract

A method of manufacturing particles, especially nanoparticles, by way of precipitation from solution on a rotating surface (1) of a rotating surface reactor is disclosed. Nanoparticles with a tight size distribution may be manufactured in bulk and without the problems of agglomeration that are associated with traditional stirred-tank reactors. Use of a rotating surface reactor allows precipitation of nanoparticles from viscous, supersaturated solutions by way of homogeneous nucleation aided by strong micromixing.
