Calcium phosphate formation in gelatin matrix using free ion precursors of Ca2+ and phosphate ions Chang MC et al. - The dense compact body of dried Ca-P/GEL nanocomposite was obtained through the fine chemical reaction of Ca2+ and Pi. The free calcium ion Ca2+, diffused from the CMV of the cation reactor greatly affected the formation of Ca–P phase. Phosphate ion species diffused through the AMV in the anion reactor definitely influenced the reaction with Ca2+. [more...]
