Evolution of the hydrated layer and crystal apatite. During the maturation and growth of the crystal, the hydrated layer, involved in a high surface reactivity, progressively decreased and led to a stable apatitic domain. The structure of the hydrated layer constitutes a pool of loosely bound ions which can be incorporated in the growing apatite domains and can be exchanged by foreign ions in the solution and charged groups of proteins (Pr).
