Versuchsvorschrift

A solid solution of amorphous calcium carbonate phosphate fluoride containing other beneficial ions was synthesized by: (1) adding 1.15 g of CaCl2, 1.39 g of SrCl2, and 0.528 g of MgCl2 to 10 mL of water; (2) adding K2HPO4, K2CO3 and sodium pyrophosphate decahydrate, 0.446 g of sodium phytate, 0.168 g of sodium fluoride, 0.0025 g of sodium hydroxyethane diphosphonate, and 1.24 mL of 14.5 M ammonium hydroxide to 52.4 mL of water buffered at pH=10.0; (3) adding 0.0386 g of chlorhexidine to 10 mL of water; (4) mixing the three solution together; (5) filtering the mixing solutions immediately; (6) washing with water and then 100% ethanol; and (7) drying the solid in a desiccator under vacuum. The approximate composition of the solid in mass % is: phosphate 18%, carbonate 8%, fluoride 2.5%, calcium 12% strontium 17%, and magnesium 2.9%.
