Wet ball milling is a green and labor-saving technology at room temperature. Wet ball milling of biochar with organic solvents (such as ethanol, hexane, and heptane) was proved to effectively enlarge the Brunauer-Emmett-Teller (BET) surface area of derived biochar up to 194 m 2 g −1, compared with 3 m 2 g −1 of the unmilled

The effects of the ball milling process and solution treatment time on the composites' microstructure, Vickers hardness, and compressive properties were studied. Increasing the ball milling speed and extending the ball milling duration reduce the size of ZrMgMo 3 O 12 particles, resulting in a more uniform dispersion within the aluminum matrix.
