Physical properties and bioactivity of nanocrystalline hydroxyapatite synthesized by a co-precipitation route

In the present work, the hydroxyapatite (HA) fine powders were synthesized through the co-precipitation in conjunction with ultrasonic vibration with various pH. The effects of solution pH on the formation and morphology of the HA powders were investigated. The obtained powders and sintered samples...
