Abstract
In this work, we prepared calcium phosphate from commercial calcium carbonate and orthophosphoric acid, and from corbicula shells and orthophosphoric acid, by a hydrothermal process. The chemical composition and powder properties of the products were investigated. Commercial calcium carbonate and corbicula shells reacted with orthophosphoric acid to produce calcium hydrogen phosphate via the hydrothermal process. The reaction between commercial calcium carbonate and orthophosphoric acid occurred in 1 h at 120 oC, while the reaction between corbicula shells and orthophosphoric acid needed over 3 h at 120 oC.
