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

抄録

The single-nanosizing of a ceramics by a top–down 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 BaZr_0.9Y_0.1O_3−α (BZY-91), which is one of the perovskite type oxides, was obtained with the combination of 0.05 mmφ zirconia beads as pulverization media and ethanol as dispersion media.
