INORGANIC-ORGANIC COMPOSITE FOR BIOMEDICAL USE

摘要

The invention relates to inorganic-organic compound substances useful for biomedical purposes. The object of the invention is to develop inorganic-organic compound materials which overcome the disadvantages of the state of art, wherein inorganic-organic compound substances for biomedical purposes possess to a large extent specifically adjustable characteristics. Inorganic initial substances form a new solid chemical compound with organic initial substances. The inorganic initial component consists of a biocompatible silicate glass and/or a silicate glass ceramic of the system SiO2-Al2O3-MgO-Na2O/K2O-F-, and/or a bioactive phosphate silicate glass and/or a phosphate silicate glass ceramic of the system SiO2-Al2O3-MgO-Na2O/K2O-CaO-P2O5F- and/or of the system SiO2-MgO-K2O-F--CaO-P2O5, and/or a bioactive phosphate glass and/or a phosphate glass ceramic of the system P2O5-Al2O3-CaO-Na2O/K2O, and/or a sintred ceramic based upon tricalcium phosphate and/or apatite. The organic initial component consists of a biocompatible, monomer-free, epoxidized polymeric hydrocarbon consisting only of the elements C, H, O having an average molecular weight &upbar& M of 2,000 to 6,000 and an epoxy equivalence EEW of 50 to 500 g. The inorganic initial component is modified by phosphoric acid.
