Preparation of porous alumina for biomedical applications through protein foaming-consolidation method

The present work reports a novel method for preparation of porous alumina using egg yolk both as consolidator and foaming agent. Suspensions with an alumina to yolk ratio of 1 in weight were prepared by stirring for 3 h and the resulting slip was poured into cylindrical shaped moulds followed by foa...
