The results demonstrated that the THA particles were successfully turned to nanosized particles via ball mill process. It can be seen that the THA nano powder was produced with the diameter ranging from 65 to 140 nm (mean value of 85 nm by Digimizer image analyzer V ) which was in good agreement with SEM results.

Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).

However, a very long ball milling time is not needed for powder refinement. Moreover, after the powders change from microscale to nanoscale, agglomeration may occur with longer milling time [26]. In addition, larger active specific surface area would be produced due to the change in particle size range from micron to nanoscale.
