Fabrication of Calcium Phosphate Bioceramics with a Uniform Distribution of Pores of a Given Size

The problem of producing biodegradable implants based on calcium phosphate porous ceramics is being solved. Highly porous ceramics with a uniform distribution of pores of a specified size is fabricated by slip casting from a suspension containing tricalcium phosphate Ca3(PO4)2 and polymeric granules 50–100 μm in size in amounts of 20 and 50 vol %, respectively, followed by heat treatment. For the chosen sintering parameters, the porosity of the ceramics is not lower than 40% and its tensile strength and biocompatibility satisfy the corrsponding requirements.
