Hydrothermal synthesis of hydroxyapatite with tartaric acid

The hydrothermal synthesis of hydroxyapatite (HA) with addition of tartaric acid (TA) is presented in the paper. The role of tartaric acid is to form a complex with the Ca ions and to help in tailoring the crystallization behavior of hydroxyapatite. A comparison is made between two situations: one i...

The role of tartaric acid is to form a complex with the Ca ions and to help in tailoring the crystallization behavior of hydroxyapatite. A comparison is made between two situations: one is characterized by the addition of tartaric acid after the precipitation of hydroxyapatite, and the other is defined by tartaric acid being added to the Ca precursor, followed by the addition of the P precursor. The crystalline particles resulted were studied by means of XRD, FTIR, SEM and TEM, and it was concluded that they consist in hexagonal lamellar crystals with lengths < 200 nm and widths < 50 nm. The difference between the two cases is that the crystallinity degree, the uniformity in crystal dimensions and the aspect ratio are higher when TA was added before the precipitation rather than to the precipitated HA. The dimensions of the achieved crystals are similar to the mineral grains found in the hard tissues of the human body.
