Research on preparation of nano-hydroxyapatite biological material

摘要

In order to obtain hydroxyapatite nanoparticles smaller particle size distribution is relatively uniform, spherical shape and the particle sample, by exploring the reaction temperature, reaction time, concentration and pH on hydroxyapatite nano size and distribution impact conditions, the results show that when the reaction temperature is 50°C; reaction time 2h; concentration 0.6mol/L; pH value of 10, the prepared nano hydroxyapatite regular shape, less agglomeration, uniform size high crystallinity. Description concentration and pH on nanoparticle size has a significant impact.
