Abstract

See full text

A method is disclosed of producing stable nanosized colloidal suspensions of particles with limited crystallinity loss, products thereof, use of the products and an apparatus for the method. In particular the present invention relates to a wet milling method with small beads wherein the size of the final particles in suspension are stabilized in the nanorange (D50<75 nm) and at the same time the particles substantially maintain the crystallinity.
