Patent ID: 8475821

Claim:
A method of manufacturing a bone prosthetic material, comprising: forming tricalcium phosphate (TCP) particle precursor particles; performing preliminary sintering on said TCP particle precursor particles at a temperature of between 1000° C. and 1300° C., so as to provide TCP particles with diameters in a range of 25 μm to 75 μm; granulating said TCP particles to produce granulated bodies with diameters in a range of 150 μm to 2000 μm; and performing sintering on said granulated bodies at a temperature of between 1135° C. and 1430° C., to produce a bone prosthetic material comprising a plurality of sintered assemblies, wherein in said sintered assemblies, the spacing between adjacent TCP particles is between 5 μm and 100 μm, and wherein in said bone prosthetic material, the spacing between adjacent sintered assemblies is between 100 μm and 400 μm.
