dc.description.abstractA mechanical activation method was used to produce a carbonate-substituted hydroxyapatite powder (CHAp) using CaHPO4.2H2O and CaCO3 as starting materials. The calcium-to-phosphorous molar (Ca/P) ratio of reactants was 1.67. Milling was performed in a sealed agate vials and balls with various parameters to optimize the process. The results showed that processing efficiency was governed by milling time, ball-to-powder weight ratio (BPR), milling speed and milling environment. The optimum parameters are as follows: milling duration of 24 hours, BPR of 10:1, milling speed of 400 rpm and dry milling. Based on these optimum parameters, subsequent milling of reactants at Ca/P ratios of 1.85 and 2.00 were also investigated to evaluate the effect of carbonate content on the properties of CHAp.en_US
