Ammonium → Tricalcium Phosphate

Participants

Reaction Steps

A solution of calcium nitrate was added with aqueous ammonium to adjust the pH value thereof to pH 12, to which was added ammonium phosphate until the molar ratio of calcium to phosphor reached 1.67. The precipitate was filtered and washed with water sufficiently to obtain a powder of amorphous calcium phosphate, to which water was added to prepare a slurry A. To 100 parts, by weight, of this slurry A was added 0.5 parts, by weight, of the same foaming agent as used in Example 1 to prepare a slurry B.
