Solubility of silicates
WebRaman spectroscopy has been employed to determine the solubility mechanisms of H 2 O in silicate melts. In melts that have a three-dimensional network structure (e.g., melts on the … WebThe solubility studies of the samples of the unsubstituted HA and 0.2-ZnSi-HA showed that the solubility of HA cosubstituted with zinc and silicate was approximately twice that of the unsubstituted HA . We concluded that the introduction of zinc and silicon ions accelerates the bioresorption of the material.
