摘要：
The effect of iron and temperature on the crystallization of dicalcium phosphate dihydrate (CaEPO4.2H(2)O, DCPD) in agarose was studied at various temperatures (27, 37 and 47 degreesC) at the physiological pH (7.4) by the single diffusion method. The spherulitic crystals of hydroxyapatite with a diameter of about 3 mm were observed in the presence of Fe at temperature of 47 degreesC. The spherulites consisted of thin, elongated needlelike crystals. Quantification of the iron incorporated in the crystals was carried out by elemental analysis. The crystals were characterized by XRD, FTIR and SEM techniques. (C) 2003 Elsevier B.V All rights reserved.
