摘要:
A composition includes particles of an inorganic component A and particles of an inorganic component B which together can form a eutectic system and react at least partly with one another at a sintering temperature, resulting in formation of at least one ternary chemical compound of the spinel type. The composition can be applied to high-temperature-stable ceramic layers, coatings and shaped bodies and also their production, their uses and compositions for producing them.
摘要:
The invention concerns a method for producing a highly-porous ceramic layer and for application of this layer onto metallic, ceramic, enameled and/or glass substrates using porous, ceramic particles, preferably aluminum oxide, titanium oxide and zircon oxide, and an inorganic binder system. The inorganic binder system contains at least one ceramic nanoparticle of a particle size of less than 100 nm, preferably less than 50 nm and particularly preferred less than 25 nm, the solvent being water. Layers produced in this fashion are suited as self-cleaning catalytically active layers e.g. in ovens, in combustion engines etc. or for general coating of substances to considerably increase their specific surface e.g. for catalytic substrates.

The invention relates to a method for producing ceramic hollow fibers from nanoscale particles and to hollow fibers produced in such a manner. The inventive method is characterized in that the ceramic material has a solids content of >25% by volume, preferably >30% by volume and is processed by means of extrusion and spinning. The hollow fiber is sintered according to conventional sintering methods. A hollow fiber produced in this manner is used for metal, polymer and ceramic matrix reinforcements, for artificial organs, for microsystems technology components, for fiber optical waveguides, for ceramic membranes, for solid electrolyte in fuel cells (SOFC), for tissue engineering and for producing extremely light ceramic parts, such as heat shields or brake systems, that are subjected to temperature stresses. The inventive ceramic batch can also be processed by means of silk screening whereby resulting in the production of filigree structures over the ceramic silk screening.

A colloidal system of ceramic nanoparticles in a dispersion medium is characterized in that the nanoparticles dispersed in the dispersion medium are distributed by 90% or more portions as unimodal nanoparticles having the same particle size in the dispersion medium, wherein the particle size variation decreases from 50%, related to nanoparticles of 1 nm, to 10% for nanoparticles of 100 nm, and the atoms and/or ions located in the surface of the nanoparticles are saturated in terms of valence in dependence on the concentration of the nanoparticles in the dispersion medium using a surface modificator such that an energetic balance of the nanoparticles in the dispersion medium is obtained. The presented colloidal system is characterized by a great stability and keeps the unimodal/monomodal nanoparticles homogeneously distributed and suspended in the dispersion medium.
