ABSTRACT:
A process for the preparation of coarse-particle dicalcium phosphate dihydrate having a virtually spherical crystal shape and a particle size range between about 63 and 450 .mu.m, preferably between about 90 and 300 .mu.m, by reacting pure aqueous phosphoric acid with aqueous suspensions of precipitated chalks, wherein an amount of suspension corresponding to the reaction product formed is removed continuously or semicontinuously and the dicalcium phosphate dihydrate is separated off, washed and dried. Also disclosed is coarse-particle dicalcium phosphate dihydrate produced by the above process.
