Abstract

We have developed new type of beads mill for the low energy dispersion of nanoparticles in liquids. This new beads mill has dual rotating axes in the vessel where the separator and rotor pin can works independently. In this machine the separator works the steadily stable separation of the dispersed nanoparticles from the beads at a high centrifugal force and the rotor pin agitates the nanoparticles by small beads under such a low rotating speed as 3m / s. In this study the dispersion performance for agglomerated titania nanoparticles have been investigated by the dual axes beads mill and small beads under various dispersing conditions. As a result, it is found that the titania nanoparticles are easily dispersed around primary particles size and their crystallinity obtained by XRD is kept well original one in comparison with the crystallinity by the conventional beads mill dispersion. This dual axes beads mill will be useful for other nanoparticle dispersions.
