Übersetzung für "Aluminium nitride" in Deutsch

A preferred catalytic coating contains platinum and aluminium nitride.

Aluminium nitride, on the other hand, has substantially improved thermal conductivity compared with silicon nitride [Ceram.

Preferred monocrystalline materials are quartz, tourmaline, gallium phosphate and aluminium nitride.

Aluminium oxide and aluminium nitride are preferred ceramic materials for hard and soft soldering.

These ceramic plates made from aluminium nitride boast extraordinary thermal conductivity and mechanical stability.

They produce aluminium nitride from gas containing aluminium and nitrogen.

The main features of sintered aluminium nitride (AlN) are:

Because this is combined with good electrical insulating properties, aluminium nitride is exceptionally suitable for applications in electrical engineering.

OECA GmbH utilizes the base substrate materials aluminium oxide (Al2O3) and aluminium nitride (AlN).

Electrical vias of for example copper are in this case embedded in a ceramic substance such as for instance aluminium nitride.

Aluminium nitride, which has excellent heat conduction properties, serves as scale protection for the non-enamelled surface parts.

Specific examples of such additives include graphite, carbon black, metal fibres, metal powders, kieselguhr, quartz, kaolin, mica, clay, CaF2, CaCO3, aluminium oxides, aluminium nitride, silicates, barium sulphate, glass fibres, carbon fibres, ceramic fibres and inorganic and organic pigments and, as mould release agents, esters of polyhydric alcohols with long chain carboxylic acids such as glycerol stearate, pentaerythritol stearate and trimethylolpropane tristearate.

Standardizing the aluminium content to less than 0.006% aims at excluding the separation of aluminium nitride which would cause a reduction of grain size.

As examples of ceramic materials to which the present invention is applicable may be mentioned nitrides such as silicon nitride, silicon aluminium oxide nitride, aluminium nitride, titanium nitride, zirconium nitride, metal oxides such as aluminium oxide, zirconium oxide, both fully and partially stabilized, magnesium oxide, carbides such as silicon carbide, titanium carbide, borides such as titanium boride, zirconium boride, and mixtures of such materials.

An a-SiC submicron powder having a specific surface area of 15.8 m2 /g (corresponding to an average particle size of 0.12 ?m), a commerical pulverulent phenol/formaldehyde resin of the novolak type, an aluminium nitride submicronpowder having a specific surface area of 11.0 m2 /g, and also acetone as the solvent for the novolak powder, were used as starting materials.

More particularly, it is possible, for example, to add graphite, carbon black, metal fibers, metal powders, kieselguhr, quartz, kaolin, mica, clays, CaF2, CaCO3, aluminium oxides, aluminium nitride, silicates, barium sulfate, glass fibers, carbon fibers, ceramic fibers and inorganic and organic pigments and, as mold release agents, for example esters of polyhydric alcohols with long-chain carboxylic acids, such as glycerol stearates, pentaerythritol tetrastearate and trimethylol propane tristearate.

From Federal Republic of Germany Patent Specification DE 38 12 266 A1, it is already known metallurgically to produce a ceramic formed body based on aluminium oxide and/or aluminium nitride and/or aluminium oxynitride powder, whereby, in the said base phase, a disperse inorganic component is present embedded, which consists of powdered aluminium metal, which can contain alloying elements and, in the case of the sintering treatment, reacts to give aluminium oxide, nitride or aluminium oxynitride.
