DETERMINATION OF PHYSICOCHEMICAL PROPERTIES AND THE THERMAL STABILITY OF HYDROXYAPATITE

Hydroxyapatite [1-3] of structural formula Ca₁₀(PO)₆(OH)₂ (HAp) and calcium triphosphate Ca₃(PO)₂ (TCP) powder sand suspensions have been characterized physicochemically. Physicochemical characteristics involved the analysis of phase composition using the X ray diffraction, the powder morphology using SEM method, determination of specific surface area by the BET method, the grain distribution of HAp water suspensions using laser diffractometer and the zeta potential as a function of suspension pH (isoelectric point) by the measurement of the electrophoretic mobility.
