The formation of a calcium-strontium apatite solid solution precursor
via mechanochemical method was described. The precursor is formed by a
process of ball-milling of a slurry consisting of a mixture of the st
arting materials; CaHPO4.2H(2)O, CaCO3, SrHPO4 and Sr(OH)(4).8H(2)O in
a zirconia pot mill for 24 h in the presence of water at room tempera
ture over the entire Ca/(Ca+Sr) compositional range. Calcium-strontium
apatite precursor obtained from bail-milling began to change to calci
um-strontium apatite upon heating at temperature over 500 degrees C.
