Modified Gelcasting Process to Prepare Porous Trifasic and Bifasic Hydroxyapatite Scaffolds

Abstract:

Article Preview

In the present work, apatite powders were synthesized at pH 10, pH 11 and pH 12 in order to give rise to biphasic and triphasic bioceramics after sintering. A modified gelcasting process, including polyethylene wax spheres addition to the suspension, is proposed in comparison to the original gelcasting method. The aim of the addition is the creation of uniform, open and interconnected pores in the body of samples.
