Preparation of Porous Hydroxyapatite Ceramics

Abstract

Abstract: The processing and the properties of porous hydroxyapatite ceramics were studied. Carbon powders with three different sizes were adopted to be pore-making
agent. HAP ceramics with porosity 30%～45%, bending strength >10MPa and pore diameter <200μm can be obtained. The results showed that porosity
firstly decreased and then increased with soaking time, while the bending strength increased continually. The pore size and distribution of the specimen can be
effectively controlled by strictly varying the size distribution of carbon powders. XRD and SEM were carried out to characterize phases and microstructure of the specimen.

Key words: hydroxyapatite, pore-making agent, carbon, porous ceramics
