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.

摘要:
The invention relates to novel mixed metal oxides of the formula AXO3 and to mixtures of such mixed metal oxides. The particle size of the inventive substances is preferably in the nanoscale region, i.e. well into the sub-μm range. The novel compounds can be used in particular for the detection of gases, in particular of incombustible gases such as CO2.

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:
In a filtration device (1) comprising a pressure-resistant housing (2) with a liquid inlet opening (3) and an outlet opening (4) for filtered matter, into which a collecting channel (12) terminates, at least one filter element (8-11) designed as flat membrane is connected to the collecting channel (12) in a pressure-tight manner. This device provides a high liquid throughput at the same time having a compact construction.
