Formation chemistry of amorphous calcium phosphates prepared from carbonate containing solutions

摘要: Recent studies on synthetic amorphous calcium phosphates have indicated a regular chemical structure similar to hydrated tricalcium phosphate with Ca/P molar ratio of 1.5. The present study, which investigates the composition formed under varying conditions pH and carbonate concentration, demonstrates that these precipitates is variable. material increases increasing pH, initial solution ratio, CaxP mM2 product, ratio. These changes in solid are produced by percentage as acid phosphate, decreases concentration solid, CO3/P It suggested biological may be rich both represent labile component bone mineral carbonate. also large fraction associated phase.
