Abstract Using NH4H22PO4、NH3·H2O和Al(NO3)3 solution as the raw materials, hydroxyapatite is prepared at high temperature and high pressure by the rapid hydrothermal method. IR and XRD are used to analyze and characterize the structure and crystallinity of the obtained samples. The result shows that hydroxyapatite which is prepared by this method has a good crystallinity, and this method is very easy in the process, which takes a short time.
