The effect of heat treatment on dissolution characteristics of synthetic hydroxyapatite

Original language description

The synthetic porous bone regeneration material based on hydroxyapatite powder was prepared by the reaction of aqueous solution calcium hydroxide and phosphoric acid. The HA granules were sintered at 700 and 1200°C. The two sizes of the granules were prepared (0.16 -0.3, 1-2 mm). The tests were carried out using unheated and heated HA granules. The initial pH of the corrosion medium was 3. XRD patterns suggested that the material was HA. (PDF database card 9-342) with low crystallinity. The micro pore size of the HA granules was less than 1?m and the specific surface area of the unheated HA granules reached 60 [m 2.g-1]. At the beginning of the interaction for the unheated and the heated HA granules the leaching of Ca 2+ and (PO4) 3- was observed. After 20 hours of exposure the ion concentrations were stabilized. The dissolution rate decrease can be caused by the solution saturation with respect to hydroxyapatite.. The heat treatment proved to have significant effect on the dissolution
