Hydroxyapatite (HAP) is a high value added bio-inorganic material, high-end HAP can be applied to the artificial bone, artificial joints and biological media separation. At present, HAP prepared by the traditional method is flaky irregular crystals, which severely limits its application. In this project, one-step synthesis of spherical crystalline hydroxyapatite with good crystallinity was carried out by homogeneous coprecipitation method. Compared with commercial HAP, the HAP synthesized by this method has high mechanical strength, high packed column flow velocity and no Agglomeration condensation, high protein adsorption capacity, high purity of the mixed protein separation characteristics. At present, we have synthesized HAP with single phase, good crystallinity and regular morphology. The resulting HAPs are agglomerated into a spheroidal shape by a hexagonal columnar monomer having a length of 1 to 2 microns, a diameter of 200 to 800 nanometers, and an aggregate size of 75 microns or more. The next step is to adjust the particle size and distribution of the HAPs and mass production of the shell as an industrial calcium source. The project participated in the first China Innovation and Entrepreneurship Competition, won the Outstanding Enterprise Award (the top 15 in Shenzhen Division).
