PRODUCTION OF TITANIA NANOPARTICLE COLLOIDAL SUSPENSIONS WITH MAINTAINED CRYSTALLINITY BY USING A BEAD MILL WITH MICROMETER SIZED BEADS

摘要

A method is disclosed ofproducing stable nanosized colloidal suspensionsof particles with limited crystallinityloss, products thereof, use of theproducts and an apparatus for the method.In particular the present invention relates toa wet milling method with small beadswherein the size of the final particles in suspensionare stabilized in the nanorange(D50 75 nm) and at the same time the particlessubstantially maintain the crystallinity.
