Abstract

Submicrometer-sized, pure calcium hydroxyapatite (HA, (Ca10(PO4)6(OH)2)) and β-tricalcium phosphate (β-TCP, Ca3(PO4)2) bioceramic powders, that have been synthesized via chemical precipitation techniques, were used in the preparation of aqueous slurries that contained methyl cellulose to manufacture porous (70%–95% porosity) HA or β-TCP ceramics. The pore sizes in HA bioceramics of this study were 200–400 μm, whereas those of β-TCP bioceramics were 100–300 μm. The pore morphology and total porosity of the HA and β-TCP samples were investigated via scanning electron microscopy, water absorption, and computerized tomography.
