Title
A novel method to produce hydroxyapatite objects with interconnecting porosity that avoids sintering
Abstract

Porous objects of carbonated apatite were prepared by mixing polyvinyl alcohol fibres (PVA) and sodium chloride as porogens with nanocrystalline carbonated apatite powder. After cold isostatic pressing (CIP) and dissolving the porogens, the bioceramic showed an interconnecting porosity with pore diameters in the range of 250–400 μm. The method can be transposed to any material that is insoluble in water (like many polymers). Such objects are promising for bone regeneration because the interconnecting porosity in carbonated apatite provides a good environment for bone attachment and ingrowth.
