The processing and properties of porous b-TCP ceramics were investigated. Naphthalene powders used as a pore-making agent. The b-TCP ceramics with a porosity of 75%, a bending strength of 5.3 MPa and pore sizes ranging from 200 ~ 500 µm were obtained. The results showed that the porosity of the ceramics decreased with increasing temperature, while the bending strength increased with increasing temperature. In addition, the phase composition and microstructures of the porous ceramics were examined by x-ray diffraction and scatting electronic microscopy, respectively.
