摘要

DICALCIUM PHOSPHATE DIHYDRATE HAVING IMPROVED MONOFLUOROPHOSPATE COMPATIBILITY AND PROCESS FOR THE PREPARATION THEREOF Dicalcium phosphate dihydrate compositions having improved monofluorophosphate compatibility are prepared by reacting a lime slurry with phosphoric acid to form a monocalcium phosphate solution, and then further reacting the monocalcium phosphate solution with additional lime slurry to a pH in the range of from above about 2.2 to below about 5.5.
