Hydroxyapatite bioceramic with large porosity

Abstract

Calcium phosphate based biomaterials have been used as bone graft with great success in the last decade. This material is employed in orthopedic and dental applications depending on their specific properties. In this work, we made a bioceramic with a large porosity, then we measured porosity, density and compressive strength of HA bioceramic. The SEM analysis was performed to show the morphology of the structure. The mechanical properties depend on the sintering of the HA bioceramic and the amount of pores. Thus, properties can be controlled by designing bioceramics with the appropriate porosities and calcination temperatures. One advantage of using gelatin is the formation of solids of any desired shape following a short time period, as the gelatin absorbs the water and expands into a solid composite form.
