• Interfacial reaction in a multiple emulsion, was carried out with the aim of preparing hollow hydroxyapatite (HAp) microspheres. The multiple emulsion was a W/O/W emulsion, made of dipotassium hydrogen phosphate solution as an inner aqueous phase, cyclohexane as an oil phase, and calcium nitrate solution as an outer aqueous phase. The phase diagrams of Ca (NO_3)_2-K_2HPO_4-H_2O system were drawn by thermodynamic computations and used to simulate the chemical process in a multiple emulsion for determining the experimental conditions. Single phase HAp was synthesized at an initial pH of 12.0. HAp with a Ca/P ratio was measured by inductively coupled plasma spectroscopy to correspond to 1.49. The product was composed of microspheres of 0.5 to 2μm in diameter. Each microsphere was composed of acicular particles with an aspect ratio of 2.5-10 with a short axis length of about 20nm.
