Paper Title:
Particle Size Control in Sol-Gel Synthesis of Nano Hydroxyapatite
  Abstract

Sol-gel method is one of the most potential techniques for mass-production of nano hydroxyapatite. In this paper, particle size control techniques, including dripping speed control, addition of several dispersants such as ammonium citrate, castor oil and silane coupling agent, as well as usage of insoluble and water soluble starch additives, were investigated. The particle size and microstructures of as synthesized hydroxyapatite were studied by X-ray diffraction, Scanning electron microscopy and dynamic light scattering. The results indicated that all the control techniques had considerable effects on decreasing the crystallite size, and the starch additives also exhibited obvious effect on preventing the agglomeration of nano crystallites during the synthesizing process.
