摘要

Porous calcium metaphosphate (CMP) ceramics were manufactured using an in situ self-foaming method. The porous CMP ceramics with different porosities and strengths, and the preparation process and the properties of the resulting material were studied. Under the conditions of a low molding pressure (<= 2.0 MPa) or low heating rate (<= 0.5 degrees C min(-1)), green specimens synthesized using only Ca(H2PO4)(2) center dot H2O (MCPM) or Ca(H2PO4)(2) (MCPA) as raw materials can be fabricated into porous bioceramics without deformation and without pore-forming agents. In this study, MCPA specimens were molded at a pressure of 80.0 MPa and the heating rate was controlled at 0.5 degrees C min(-1). The synthetic biomaterial showed a porosity of 38.0% and a strength of 48.0 MPa.
