Abstract
The use of calcium phosphates as biomaterials was
largely developed during the last decades. Among the phosphorous compounds
solid minerals of biological interest, the dicalcium phosphate dihydrate,
(DCPD or brushite) (CaHPO4, 2H2O), disserves a special attention.
It can be prepared in different ways. The manufacture of inorganic
phosphate, it is usually produced by the acidulation of limestone form of
calcium with phosphoric acid. The synthesis of this phosphate depends on
many operational parameters. This study was performed in order to verify the
influence of temperature and the time on the chemical purity and the yield
of precipitation. All the samples were characterized by X-ray diffraction,
infrared spectrometry and chemical analysis.
