摘要

DICALCIUM PHOSPHATE DIHYDRATE HAVING IMPROVED MONOFLUOROPHOSPHATE COMPATIBILITY AND PROCESS FOR THE PREPARATION THEREOF Dicalcium phosphate dihydrate composition having improved monofluorophosphate compatibility are prepared by the addition of magnesium oxide and pyrophosphoric acid to the reaction mixture, and terminating the reaction by which the dicalcium phosphate dihydrate is formed at a low pH.
