Abstract

The aim of this study was to elaboration of β- TCP foams with good compressive strength, by the polymeric sponge technique that typically produces open-cell structures: polyurethane impregnated with ceramic slurry, is burned out leaving a porous ceramic. For experiments was used two type of the polyurethane with different pore sizes. Porous samples were characterized with optical Microscope Carl Zeiss NU2, Material Testing Machine Zwick T1-FR005TN, and the β-TCP suspensions with the ZetaPlus Brookhaven type. The preliminary results evidenced a macroporous structure formed (with pose size between 150-450 μm) characterized by good compressive strength in the range of the cancellous bone. Future work will focus on improving the strength of these open porous calcium phosphate ceramics..
