Polyurethane　(PU)　foam　used　as　gelcast　was　immersed　in　calcium　phosphate　cement　(CPC)　paste,　a　layer　of　the　CPC　was　coated　on　PU　foam.　After　the　CPC　hardened,　the　CPC-PU　composite　was　sintered　at　1200°C.　During　the　sintering　process,　the　PU　foams　in　the　CPC-PU　composite　underwent　thermal　decomposition,　resulting　in　the　formation　of　a　sintered　porous　hydroxyapatite　(HA)-based　calcium　phosphate　ceramic.　The　sintered　porous　ceramic　was　immersed　in　the　CPC　paste　repeatedly　at　room　temperature.　The　material　with　a　desired　pore　size　and　a　high　porosity　was　obtained.　The　porous　material　also　possesses　a　good　interconnection　and　a　compressive　strength　comparable　to　that　of　cancellous　bone.　An　in　vitro　investigation　shows　that　the　obtained　porous　material　has　good　biocompatibility.
