| description | The hydrothermal system has been widely used in recent years for the synthesis of materials, especially in the synthesis of nanostructured materials. The present work aimed to synthesize hydroxyapatite, since it is characterized by being a biomaterial widely used in bone replacement procedures. The synthesis of this material was conducted via the hydrothermal system combined with the influence of the microwave. The materials obtained in this synthetic route were compared with the material obtained by synthesis in hot plate. Also explored was the influence of synthesis time (10, 20 and 30 min). The synthesized materials were analyzed by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. The results showed that the synthesis heating plate is capable of generating particles of smaller crystallite size and crystallinity equivalent to those of the materials synthesized in hydrothermal system assisted by microwaves. Moreover, the hydrothermal system was only effective in the synthesis of hydroxyapatite for 30 min. Times smaller synthesis in hydrothermal system generated with a mixture of hydroxyapatite with brushite and monetite. |
