The ball-milling process strongly influences the formation of uniform-sized spherical particles with a high surface area. Fully crystalline monoclinic ZrO 2 nanoparticles with an average particle size of 64 nm (d 50) and the specific surface area of 126 m 2 /g were obtained. In addition, the sodium-stabilized cubic ZrO 2 nanoparticles with an ...

A high-energy ball-milling method has also been reported for the synthesis of BPQDs. Different from the case of bulk BP prepared from RP via HEMM method, the bulk BP crystals were directly used as the precursor, followed by subjecting to the milling process for 6 h with ethanol as the solvent . Subsequently, the dispersion was centrifuged at ...

The cryomill is a vibratory mill having a single ball with diameter 5 cm and vial 9.5 cm with volume of 250 cc. Thus, ball amplitude 2 mm was maintained through milling using tungsten carbide (WC) ball-vial. The milling chamber was continuously purged using argon (Ar) gas to protect the powder from oxidation during milling.

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills ...

Ball milling (Fritsch, Pulverisette 7) was performed at 300 to 700 rpm and 4 to 12 cycles. One cycle consisted of 10 min of grinding and 5 min of resting. After grinding, distilled water (10 mL) was added into the ball-mill chambers and rotated at low speed (200 rpm) for 5 min. At this stage, the dissolution of SSW-derived chitin occurred.
