Abstract
Hydroxyapatite (HAP) crystals with hexagonal structure have been successfully synthesized by using EDTA(ethylene diamine tetraacetic acid) as chelate under hydrothermal condition. The as-prepared HAp powders were characterized by XRD and SEM. The XRD result indicated that the products were preferentially oriented along c-axis. The SEM photographs showed that the morphology of the HAp crystals was well controlled by the reaction parameters such as temperature, pH value, and the molar ratio of EDTA/Ca.
