Dicalcium Phosphate an overview ScienceDirect Topics

6.2.2.4 Calcium phosphate bone cements. Calcium phosphate bone cements first appeared in the 1980s to offer the potential of in situ molding and injectability. Several combinations of calcium compounds, like TCP and dicalcium phosphate, are used in the formulation of bone cements; however, the end product is normally based on a calcium

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4.It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.Dicalcium phosphate is used as a food additive, it is found in some

Calcium Phosphate an overview ScienceDirect Topics

S.A. Guelcher, in Injectable Biomaterials, 2011. 15.4 Calcium phosphate bone cements. Calcium phosphate cements (CPCs) have been investigated extensively as injectable bone replacement biomaterials due to their similar chemical composition to the mineral component of bone. A limitation of CPCs is their brittle mechanical properties and slow degradation in vivo. 2 Therefore, enhancing the

Effect of processing conditions of dicalcium phosphate

Dicalcium phosphate cements (brushite and monetite) are resorbable biomaterials with osteoconductive potential for bone repair and regeneration that have yet to gain widespread commercial use. Brushite can be converted to monetite by heat treatments additionally resulting in various changes in the physico-chemical properties.
