| Abstract: | Objective To explore the process of modifying coral hydroxyapatite by nmZnO under the different conditions. Methods Coral hydroxyapatite was modified by zinc nitrate sol-gel method at 70 ℃ in weak acid environment. White granular porous composite materials were obtained by ultrasonic, rotary stirring, drying and calcination. The surface characteristics of the modified materials were observed by scanning electron microscope. Results The results showed that the distribution and size of nmzno particles on the coral hydroxyapatite surface were different under the different raw material ratios. In the process of heat treatment, different holding temperature and holding time would lead to the change of carbon removal effect and structural integrity of materials. Conclusion Coral hydroxyapatite surface can be modified by zinc nitrate sol-gel method. The particle size of nano zinc oxide is less than 100 nanometers. The agglomeration problem of nano-particles is solved. |
