Shaped, composite bodies are provided. One portion of the shaped bodies comprises an RPR-derived porous inorganic material, preferably a calcium phosphate. Another portion of the composite bodies is a different solid material, preferably metal, glass, ceramic or polymeric. The shaped bodies are especially suitable for orthopaedic and other surgical use.

Disclosed is a method for producing a transparent and homogenized polymeric sol of a calcium phosphate compound, containing apatite and having excellent wettability and bioactivity, according to a sol-gel synthesis, and a method for coating the polymeric sol on a metal implant, in which the polymeric sol is coated on the metal implant and then heat-treated to form a dense coated layer strongly bonded to the metal implant. The polymeric sol is obtained by process of preparing a calcium salt solution, containing calcium ethoxide dissolved in organic acid, and a phosphate solution, containing triethyl phosphite or triethyl phosphate dissolved in the organic acid, mixing the calcium salt solution with the phosphate solution to produce a mixed solution, and aging the mixed solution.
Uniform β-tricalcium phosphate porous nanospheres with substructures are prepared by a solvothermal method using (CH3O)3PO as the organic phosphorus source and they demonstrate excellent biocompatibility.

A molded article simulating the appearance of natural plantation crepe rubber and a method for producing this article. Styrene/butadiene linear or radial block copolymer having a polymerized styrene content of the range of about 2Q to about 50 weight percent of the total block copolymer and resinous polymer of vinylsubstituted aromatic compound in the range of about 10 to about 60 parts resinous polymer per 100 parts block copolymer are blended with a sufficient amount of polarizing agent to achieve rapid heating through response to microwave treatment. The composition is melted, molded against a surface mirroring the appearance of plantation crepe rubber, and removed from the mold as an article simulating plantation crepe rubber. In an embodiment of the invention with chemical blowing agent incorporated into the molding composition, an amount of the molding composition is introduced with the mold that upon activation of the blowing agent during the molding operation produces a molded article having a normally dense skin with a microporous interior.
