Zinc-doped biphasic calcium phosphate (BCP) powders have been synthesized via sol-gel method. The dopant concentration ions were adjusted at 1, 2, 3, 5, 10 and 15 mol%. The powders have been calcined at varying temperatures ranging from 500-900 °C and then characterized by XRD, FTIR, TG/DTA, TEM and FESEM data. X-ray diffraction patterns
Nisbah kalsium kepada fosfat ialah 1.67, serupa dengan nisbah tulang dan gigi asli. Corak pembelauan sinar-X menunjukkan kedua-dua nanorod itu memiliki fasa hablur yang hampir tulen dengan kehadiran fasa kedua yang boleh diabaikan.

Magnesium-doped biphasic calcium phosphate (Mg-BCP) powders were successfully prepared using Ca(NO3)2.4H2O and (NH4)2HPO4 as the precursors and Mg(NO3)2.6H2O as the source of the dopant.
The aim of this study was to investigate the thermal behavior of Mg-doped calcium phosphate compounds. Nanocrystalline HA and β-TCP mixtures containing different magnesium contents were synthesized via an alkoxide sol gel method.The ratio of (Ca+Mg)/P was kept constant at 1.67, and the Mg content ranged between 0 and 3 mol%.

Here we present magnesium-doped biphasic calcium phosphate (Mg-BCP) using chemical doping process through a solgel method. Mg-BCP was produced using calcium nitrate tetrahydrate and di-ammonium hydrogen phosphate as the precursors for calcium and phosphorus, respectively. Magnesium nitrate was used as the source of the dopant.
