ABSTRACT:
A granular directly compressible anhydrous dicalcium phosphate having a particle size sufficient for efficient direct compression tableting, preferably at least 90 percent greater than 44 microns, a dentin abrasion value of less than 150 and a surface area of greater than 5 meters.sup.2 /gram can be prepared by dehydrating particles of soft dicalcium phosphate dihydrate of a particle size insufficient for direct compression tableting, preferably at least 10 percent less than about 44 microns such as by heating at a temperature sufficient to form anhydrous dicalcium phosphate. The dehydrated particles are then granulated with a binder. The product is a granular anhydrous dicalcium phosphate exhibiting good compressibility and flowability while being in an anhydrous state.
