Physicochemical Properties of Magnesium-doped Hydroxyapatite Nanoparticles Prepared by Incipient Wetness Impregnation Method
Nanocrystalline hydroxyapatite powders are successfully synthesized by sol-gel method with calcination temperature at 600 °C for 2 h. The molar ratio of Ca: P is kept at 1.67 as hydroxyapatite (HAp). Different weight percents of the magnesium-doped hydroxyapatite (xMg/HAp, x = 0, 1, 3, 5, 7 and 9 wt...
