Definitions
- the invention relates to a ceramic material.
- Ceramic materials offer a variety of applications. Their composition can be tailored by specific addition of certain elements and / or their compounds to the intended use.
- Aluminum oxide and zirconium oxide, for example, are ceramic materials which are processed individually or in combination with one another inter alia to cutting tools, catalyst supports or prostheses.
- Hardness, aging resistance, water wetting behavior, and high thermal conductivity are properties known of alumina sintered compacts, high strength, and high fracture toughness, that is, damage tolerance, are properties known from zirconia sintered compacts.
- an aluminum oxide material in the following composition in the sintered body is suitable as a material, in particular for use in the field of medical technology, for example for the production of orthoses and endoprostheses, such as hip joint and knee joint implants.
- Alumina in appropriate addition to 100 wt .-%.
- Dominant structural component of such a combination of materials is the aluminum oxide. Therefore, the property-determining characteristics such as hardness, Young's modulus and thermal conductivity close to the properties of pure alumina.
- the constituents zirconium oxide and optionally strontium aluminate are incorporated in the aluminum oxide matrix.
- the raw materials are preferably used in high purity. Due to the high purity of the raw materials, grain boundary phases are formed only to an extremely small extent.
- the strontium aluminate forms characteristic platelet-shaped crystallites, platelets, which contribute significantly to the increase in strength.
- the constituents zirconium oxide and strontium aluminate contribute to increasing the fracture toughness, which is about 60% higher than with pure aluminum oxide.
- the strength is increased almost by a factor of 2
- the damage tolerance that is, the property of the component, even with a possible damage still retain a high residual strength.
- the crack path is surprisingly deflected, so that additional energy is absorbed in the crack propagation.
- a peculiarity of the material according to the invention is to be considered that the two mechanisms mutually reinforce, so that the effective increase in the fracture toughness is even greater than would be expected by simple addition of the individual mechanisms.
- Al 2 O 3 The content of Al 2 O 3 supplements from 72.65 wt .-% to 74.54 wt .-%. Commodity related contaminants ( ⁇ 0.05% by weight) are possible but not listed separately because of their minority.
- the production of sintered molded articles from the material according to the invention takes place by means of conventional ceramic technology.
- the properties of the sintered body from the material according to the invention can still be reinforced by inclusions. It is thus possible to mix whiskers and / or fibers into the material before forming a sintered body or incorporating reticulated structures or fabrics into the green state material.
- the whiskers, fibers or nets or webs must be made of a material that does not interact with the ceramic material in such a way that deterioration of its properties occurs. In addition, the material must not change during sintering in such a way that the material is damaged.
- Sinterform body which are made of the material according to the invention, surprisingly combine the respective best properties of competing ceramic materials alumina and zirconia for implant applications in itself: hardness, aging resistance, water wetting behavior and high thermal conductivity are properties of sintered form bodies of alumina High strength and high fracture toughness, that is damage tolerance, are properties known from zirconia sintered compacts.
