A method for producing a ceramic osseoconductive bone substitute material, the bone substitute material, intervertebral disk implants containing the substitute bone material, and to methods of using the bone substitute material.

Ceramic bone substitute material and method for the production thereof

The present invention relates to a bone substitute comprising a core based on hydroxyapatite (HA), obtained from at least one porous wood, or based on collagen fibers and hydroxyapatite, and a shell, based on hydroxyapatite (HA) or silicon carbide (SiC), obtained from at least one wood having a lower porosity than the at least one wood of the core. The porous wood has a total porosity of between 60% and 95%, preferably between 65% and 85%, and it is selected from amongst the choices of rattan, pine, abachi and balsa wood. The wood of the shell has a porosity of between 20% and 60%, preferably between 30% and 50%. The bone substitute is utilized for the substitution and regeneration of bone, preferably for bones subjected to mechanical loads, such as long bones of the leg and arm, preferably the tibia, metatarsus, femur, humerus or radius.

Implants for 'load bearing' bone substitutions having hierarchical organized architecture deriving from transformation of vegetal structures

Ceramics are made of preceramic paper or board structures in a particular shape previously represented in a paper structure, in which the preceramic papers or boards have a content of ceramic fillers between 30 and 95 wt-%, with the ceramic fillers having a particle size &#x3c;30 &#x3bc;m. A method for manufacturing such ceramics and the use thereof are also provided.

Ceramics made of preceramic paper or board structures, method of producing the same and use thereof

The invention concerns a process for the production of a porous &#x3b2;-SiC-bearing ceramic molded body that includes an aluminum oxide layer at the surface of the pores and passages of the porous &#x3b2;-SiC-bearing ceramic molded body. The invention further concerns a porous &#x3b2;-SiC-bearing ceramic molded body which has pores of a mean pore size in the range of between 0.1 urn and 50 &#x3bc;m and an aluminum oxide layer at the surface of the open pores and passages.

Porous &#x3b2;-SiC-containing ceramic molded article comprising an aluminum oxide coating, and method for the production thereof

The invention relates to a process for the production of a molded porous ceramic article containing &#x3b2;-SiC, which process comprises the following steps: the preparation of a molded article containing silicon and carbon and the subsequent pyrolysis and siliconization of the article containing silicon and carbon to form SiC. The invention further relates to a molded porous ceramic article containing SiC which has been produced from a molded article containing silicon and carbon.

A sorption rotor has end faces and is rotatably journaled to travel during a revolution through an inflow sector and an outflow sector. The rotor is made of a matrix material having a honeycomb structure with axially throughgoing flow passages. The matrix material is constituted of cellulose paper modified by a ceramic material infiltrated by a sol-gel system or a gel-forming low-viscosity liquid into the matrix.

The invention relates to polymer ceramic composite materials with a virtually zero shrinkage compared to the original model after concluding partial pyrolysis and with a comparable thermal expansion behavior (preferably in an application range of 400&deg; C. or less) to metal construction materials, in particular gray cast iron or steel, which are obtainable by methods described below; corresponding composite constructions and molded parts; and methods for producing and using these materials, composite constructions and molded parts. The polymer ceramic composite materials can for instance be used instead of or in contact with steel or gray cast iron temperature-proof molded parts, predominantly in mechanical engineering, without postmachining after the creative forming.

A molded part of a ceramic material derived from polymers includes a composite body of a single-phase or multi-phase, amorphous, partially crystalline or crystalline matrix of silicon carbide (SiC), silicon nitride (Si N ), silicon dioxide (SiO ) or mixtures thereof. The matrix contains graphite inclusions and the density of the ceramic material is at least 85% of the theoretical value. The molded part is produced by subjecting a mixture formed of a polymer component in an amount of 30 to 80 wt. % referred to the total weight of the mixture, fillers in an amount of 0 to 30 wt. % and graphite in an amount of 10 to 70 wt. %, to a forming process with heating to effect crosslinking of the polymer components, followed by a pyrolysis process. In particular, the molded parts are produced from polymers of the group including polysilanes, polysiloxanes, polysilazanes or polycarbosilanes. A process for producing ceramic molded parts and a sliding element having a molded part are also provided.

An article that is particularly well suited for use as a gas turbine engine component has a metallic substrate and a ceramic thermal barrier layer including a mixed metal oxide system comprising a compound selected from the group consisting of (i) a lanthanum aluminate and (ii) a calcium zirconate, the calcium in which is partially replaced by at least one calcium-substitute element, such as strontium (Sr) or barium (Ba). In addition, the lanthanum in the lanthanum aluminate can be partially replaced by a lanthanum-substitute element from the lanthanide group, particularly gadolinium (Gd). A process for producing such an article comprises providing a pre-reacted mixed metal oxide system as described above and applying it to the substrate by plasma spraying or an evaporation coating process.
