COMPOSITE MATERIAL BASED ON FLUOROHYDROXYAPATITE AND PARTIALLY STABILISED ZIRCONIUM DIOXIDE FOR BONE DEFECT REPLACEMENT Russian patent published in 2016 - IPC A61L27/04 A61L27/12 

FIELD: medicine.

SUBSTANCE: invention relates to by bioceramic materials intended for production of bone implants and/or defect replacement in various bone pathologies. Technical result is increased strength of materials in a system of 40-60 wt% fluorohydroxyapatite - 40-60 wt% of zirconium dioxide, containing 2 to 5 wt% of sintering additive. As a result of using said additive, sintering was carried out at low temperatures 1300-1330°C, which enabled to preserve initial phase composition and production of composite material with high mechanical properties: flexural strength not less than 300 MPa and fracture strength not less than 4 MPa*m^1/2.

EFFECT: high strength of composite materials makes them applicable for making implants, capable of withstanding physiological load in body.
