Dicalcium Phosphate Dihydrate

 

(CaHPO4·2H2O), a mineral phosphate fertilizer. Dicalcium phosphate dihydrate is a white or light-gray powder that is dusty when introduced into the soil. It does not cake and is efficiently sowed by fertilizer spreaders. It contains 27-35 percent P2O5 and is produced by the reaction H3PO4 + Ca(OH)2 = CaHPO4·2H2O. A basic fertilizer, it is used with all types of cultures and soils, although its greatest effectiveness is with acid soils. Dicalcium phosphate dihydrate is also used as a mineral feed supplement for animals.

Since their first development in the 1980's, calcium phosphate cements (CPC) have attracted considerable attention because these materials set like cements and form nanocrystalline hydroxyapatite (HA) (1) or microcrystalline dicalcium phosphate dihydrate (DCPD) (2) as the major product.
Dicalcium phosphate anhydrous (DCPA) and dicalcium phosphate dihydrate (DCPD) (5), octacalcium phosphate (OCP) (6) and other calcium phosphate compounds (5), (7-9) are used either as components or formed as products of calcium phosphate bone cements.
CPCs of different compositions can form different end products such as hydroxyapatite (HA), octacalcium phosphate, and dicalcium phosphate dihydrate (DCPD), also known as brushite.
