Abstract
Thermodynamic functions of solution of apatites in water under standard con ditions (DeltaG(s), DeltaH(s), and DeltaS(s)) are calculated. The influence of the enthalpy and entropy factors on the possibility of spontaneous diss olution is analyzed. The coefficients a, b, and c for polynomials that expr ess the temperature dependences of the activity product for a number of apa tites in the temperature range of 298-473 K are calculated. The thermodynam ic allowability of the synthesis of apatites in water solutions is estimate d.
