摘要：

Nano-sized hydroxyapatite (HAp) powders were synthesized by a microwave-hydrothermal method using H3PO4 and Ca(OH)(2) as starting materials. The applied microwave powers and mole ratio of Ca/P were served as powerful factors in the synthesis of calcium phosphate. In the case of relatively low microwave power of 450 W and Ca/P ratio of 1.57, the mixed calcium phosphate compounds were detected in the synthesized powders. But in the case of running at 550 W and 1.67(Ca/P), the synthesized powder showed the monophase of HAp having two kinds of morphologies. One was a needle shape with 5 similar to 15 nm in width and 20 similar to 50 nm in length, and the other was a spherical shape of 10-40 nm in diameter.
