27 results about "Amorphous calcium phosphate" patented technology

Amorphous calcium phosphate (ACP or ATCP) is a glassy precipitate of variable composition that is formed in double decomposition reactions involving a soluble phosphate and calcium salts (e.g. (NH₄)₂HPO₄ + Ca(NO₃)₂) performed under carefully controlled pH conditions. The precipitate will either be "amorphous tricalcium phosphate", ATCP, or calcium deficient hydroxypatite, CDHA, Ca₉(HPO₄)(PO₄)₅(OH), (note that CDHA is sometimes termed apatitic calcium triphosphate). The composition of amorphous calcium phosphate is CaₓHy(PO₄)z·nH₂O, where n is between 3 and 4.5. Precipitation from the moderately supersaturated and basic solution containing magnesium produces amorphous magnesium calcium phosphate (AMCP) in which magnesium incorporated into the ACP structure.
