“…With the aim of identifying the nature of the solid phases of these isotherms, the mixtures of compositions appropriately chosen were prepared. These mixtures denoted N 1 , N 2 , N 3 and N 4 (Figure 2), were maintained separately at 45 ± 0.1 °C and slowly stirred at least for one week, assuming that equilibrium was reached [11]. The obtained mixtures are composed each of a liquid phase in equilibrium with a solid phase.…”

The solid-liquid phase equilibria of the system H3PO4-Ca(OH)2-H2O were studied under air pressure using a synthetic method based on conductivity measurements. Two isotherms at 15 and 45 °C were completely defined. The stable solid phases which appear in this range of temperature are hydroxyapatite (Ca10(PO4)6(OH)2), calcium hydrogen phosphate dihydrate (CaHPO4.2H2O), calcium hydrogen phosphate anhydrous (CaHPO4) and calcium dihydrogen phosphate monohydrate (Ca(H2PO4)2.H2O). These solid phases were characterized using X ray diffraction.
