The millimeter sized particles are further ground by using ball milling to achieve micrometer sized particles. Finally, the micrometer sized powders were dispersed in IPA solution at 10-15% of solid concentration and then ground on a bead mill using 0.2 mm zirconia beads to achieve nanometer sized particles.
