Preparation of Calcium-Deficient Carbonated Hydroxyapatite Nanoparticles by Microwave Process
In this paper, carbonated calcium-deficient hydroxyapatite (d-HA) nanoparticles were synthesized by a chemical precipitation method assisted with microwave irradiation. The important factors which effected on the synthesis process, such as pH value, time and the power of microwave irradiation on the Ca/P molar ratios of d-HA were discussed. The experimental results showed that carbonated d-HA nanoparticles could be quickly synthesized by irradiating the reaction solution for about 1h under moderate microwave power and pH value ranging from 8 to 9.
