The utility model discloses a kind of gradient-structure calcium phosphate biological ceramic, described material comprises three kinds of different gradient crystal structure layer such as nanocrystalline structure surface layer, Nano/micron crystal structure transition zone, micro-crystal structure centre layer.Described material obtains the pottery with nanometer, the change of micro-crystal gradient-structure by setting up sintering temperature Gradient distribution field.The nanocrystal layer of material gives the biological activity of material uniqueness, micro-crystal layer ensures the mechanical property of material, therebetween gradient transition, combine closely, and combine the mechanical property with matching materials and natural sclerous tissues by adjustment Nano/micron Rotating fields, thus meet the multi-functional demand object of biomaterial. |
