Characterization of Nanohydroxyapatite Prepared by Precipitation from Calcium Α-d- Heptagluconate Precursor Solutions
نویسنده
چکیده
Calcium deficient nanohydroxyapatite (nanoHap) powders were synthesized by co-precipitation of calcium α-D-heptagluconate hydrate and diammonium hydrogen phosphate solutions. TEM and HRTEM images of powders after the drying of products showed that the reactant concentration affected the sizes and morphology of particles. Small changes were found in phase composition of nanoHap powders synthesized from variously concentrated reactant solutions. The biphasic mixtures of hydroxyapatite and β-tricalcium phosphate (β-TCP) were formed after annealing at 1000°C.
