実験手順
A quantity of dicalcium phosphate dihydrate was prepared as in Examples 1 and 2 except that the slaked lime slurry was added to the monocalcium phosphate solution until the pH reached about 5.6 and then pyrophosphoric acid was added until the pH was reduced to about 5.3; no further slaked lime slurry was added.
