Abstract
The invention belongs to inorganic non-metallic materials science, Biofunctional materials field.The invention provides a kind of incline ceramic material of biologically active, this material has the feature of structural ceramics a side, and its composition is stable or PSZ, or aluminum oxide, zirconium white composite alumina; The feature of another side biologically active pottery, its composition are hydroxyapatite (HA), or are made up of TCP, bioactivity glass and mixture thereof.Chemical ingredients and physicochemical property between two sides are continuous variation.This material has 300MPa above bending strength and excellent biological compatibility, can be used as substituting or repair materials of osseous tissue.
Description
The invention belongs to inorganic non-metallic materials science, Biofunctional materials field, the present invention relates to a kind of high-intensity bioceramic material.Because biological ceramics has than metallic substance and the more excellent biocompatibility of macromolecular material, so recent two decades comes, and is developed faster, existing bioceramic material is broadly divided into two big classes, and the first is with pure AI
2O
3Pottery is the high-intensity bio-inert ceramic of representative.Characteristics are nontoxic, non-carcinogenesis, stabilizer pole in vivo, and can keep high physical strength for a long time.In recent years, also have some to be usually used in the technical ceramics (or being called structural ceramics) of structured material, as the report in the applied research of biomedical sector such as zirconium white, silicon nitride, titanium nitride.It two is to be the bioactive ceramics (comprising the bioactivity glass that contains the phosphoric acid salt crystallite) of representative with synthesizing hydroxylapatite (HA), tricalcium phosphate (TCP), be characterized in, has excellent biological compatibility, can produce directly with osseous tissue and combine, be applied in fields such as tooth section and decorative surseries.But all there are some shortcomings in this two classes material, and the former is that the top layer is often held by fibrous tissue after implanting living body, can not directly engage with bone interface, and life-time service can be loosening with the interface generation of osseous tissue at pottery.The latter is because physical strength is lower, and the intensity of bending strength and cortex bone is suitable, uses so be only limited at non-weight bearing area.
Recently, aspect the intensity that improves bioactive ceramics, JP6140884 discloses a kind of with partially stabilized ZrO
2Pottery (PSZ) is a core, and the top layer applies the thick TCP of 50U, has high bending strength (1100MPa).The result of study (Japanese " pottery " 1989 No2, P, 164) that the investigator of Japan AGC company in 1989 has disclosed them adopts silicon nitride crystal whisker that HA is carried out compound enhancing, and its bending strength reaches 400MPa.The Osaka, Japan industrial technology test employing ZrO that reported in 1988
2The result of compound enhancing HA and TCP (Japan " fine ceramics " 88 years No9P.106-111), its bending strength reaches 350-400MPa.
, there is some difference because the coefficient of expansion of bioactive ceramic coating and Young's modulus are with body material, behind the implantable bioartificial body, and under the repeated stress effect, the possibility that has generation to peel off; The compound enhancing with particle dispersion of above-mentioned whisker needs realize that under hot pressing condition its goods and shape will be restricted, and ceramic whisker has certain carcinogenesis.
The purpose of this invention is to provide a kind of biologically active that can under normal pressure-sintered condition, prepare and high-intensity ceramic artificial bone material.
Feature of the present invention is that this material has the feature of structural ceramics a side, and its composition is stable or PSZ; The feature of another side biologically active pottery, its composition are hydroxyapatite or TCP, bioactivity glass, or their mixture.Chemical ingredients and physicochemical property between two sides are continuous variation.The AL that the present invention adopts
2O
3Material purity is more than 99.5%, and particle diameter is in 0.01-50 μ scope; The ZrO that adopts
2Raw material particle size is at 0.01-50 μ scope, ZrO
2Raw material is through CaO, MgO, Y
2O
3, a kind of in the oxide compound such as CeO or one to three kind of oxide compound stablize or partially stabilized, the content of its stablizer is in the 0.01-20% scope, HA raw material and TCP raw material adopt the artificial synthesis preparation, its Ca/P ratio is respectively 1.65-1.69 and 1.40-1.62.After raw material is made respectively and had mobile slip, regulate pressure system through ratio and make green compact, 1200-1650 ℃ of scope in normal pressure-sintered stove preferably burnt till 1450-1600 ℃ of scope, and this material can be made en plaque or tubular body.
This material has 300MPa above bending strength and excellent biological compatibility, this stupalith is owing to realized the continuous variation of chemical composition and physicochemical property, both the biologically active pottery can with the direct bonded performance of osseous tissue, have the good characteristic of structural ceramics strength high toughness again, in giving birth to body, use to keep its biological safety and mechanical stability for a long time.
Embodiment 1
With the AL of particle diameter in 0.01-0.5 μ scope
