Abstract
Porous hydroxyapatite bioceramics were developed by a new direct consolidati on method based on the foaming capability of egg white and on its gelling pr operties on heating, thus acting both as pore former and consolidator agent. The bubble forming capability of fresh egg white, due to the presence of a globular protein - albumen, allows the formation of a stable foam when added to a ceramic suspension. Adding a sufficient amount of the globular prot ein to the suspension revealed to be crucial to control either the pore volume fraction as well as the gelling behaviour and the rigidity of the green bodies. This consolidation method can be perform ed in nonporous moulds, enabling materials with controlled porosity to be obtained by varyin g the egg white content in the slip composition. After drying, burnout and sintering, materials wit h ultimate porosities close to 75 % were obtained.
