Abstract

Dicalcium phosphate anhydrous (DCPA) and dicalcium phosphate dihydrate (DCPD) particles were prepared through the reaction between calcium nitrate and dipotassium hydrogen phosphate in a solution and a multiple emulsion. Organic compounds were added into the phosphate solution with the aim of modifying the morphology. Large parallelogrammic particles of DCPD were obtained with no additive. By adding 2-aminoethanol, the product was changed to rhombic in shape and reduced to one-twentieth in size, and the phase was DCPA. In the multiple emulsion, microspheres composed of DCPA were prepared. They were constructed by flaky, primary particles. The crystalline phase and morphology were affected by the concentrations of surfactants in the oil and outer aqueous phases.
