Single-nanosize pulverization of solid oxide by means of a wet planetary-bead-milling

Abstract

The single-nanosizing of a ceramics by a topdown method was demonstrated using a "wet planetary bead-milling" method, which is the combination of bead milling and planetary milling. By using the planetary bead-milling, single-nanoparticles (about 2 nm) of BaZr0.9Y0.1O 3-α (BZY-91), which is one of the perovskite type oxides, was obtained with the combination of 0.05mmφ zirconia beads as pulverization media and ethanol as dispersion media. © 2012 The Ceramic Society of Japan.
