| Summary: | Nanometer sized hydroxyapatite particles are synthesized via wet chemical
precipitation and characterized. This research studies how key parameters such
as the pH of synthesis, and also the reaction, aging and calcination
temperatures affect the size and phase purity of the hydroxyapatite produced.
The main aim is to determine the optimum condition for producing phase-pure,
nano-sized hydroxyapatite with minimum agglomeration, to be used as bone
replacement material.
A 0.2 M solution of Ca(N03)2.4H20 (Calcium Nitrate Tetrahydrate) and a 0.12
M solution of (NH4)2HP04 (Diammonium Hydrogen Phosphate) are coprecipitated
in the presence of a dispersant. |
