In a past study we have found a marked difference in the kinetics of the high temperature decomposition of hydroxyapatite between foams and dense pellets. Foams decompose much faster because of the short transport distances to the external environment. This presentation will describe a series of experiments where the pore structure of a ceramic was used to control the kinetics of hydroxyapatite decomposition. A direct foam emulsion technique was used to create structures that ranged from highly open foams to denser closed foams. The effect of the change in pore structure on the decomposition and cracking in the ceramic and the implications of these properties for regenerative medicine applications will be presented.
