Calcium Carbonate → Tricalcium Phosphate

Participants

Reaction Steps

β-Tricalcium phosphate was prepared by heating a mixture of dicalcium phosphate anhydrous (DCPA, Baker) and calcium carbonate (CC, Merck) in a molar ratio of 2:1 up to 1050° C. for 24 h, followed by quenching to room temperature. The sintered cake was crushed with pestle and mortar and sieved until it passed through a 355 μm sieve. The material was ground in a ball mill to a medium particle size d50 of 9.8 μm. Monocalcium phosphate monohydrate with a medium particle size d50 of 23.3 μm was purchased from Baker and used as received. Both materials were mixed in equimolar amounts in a coffee grinder for approximately 20-30 s.
