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.
