摘要： Provided are palladium-containing powders and a method and apparatus for manufacturing the palladium-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications. Powders may have high resistance to oxidation of palladium. Multi-phase particles are provided including a palladium-containing metallic phase and a second phase that is dielectric. Electronic components are provided manufacturable using the powders.

摘要： A hard metal grade powder is produced from hard material, metal binder, and non-water-soluble pressing aid components, by forming a slurry containing the components and pure water as a liquid phase and then drying the slurry. Here, the hard material and metal binder components are first milled in water, to form a slurry. Then the pressing aid components are added to the slurry in the form of an emulsion produced with the aid of an emulsifier with the addition of water.

摘要： A new method and apparatus for manufacturing powders of cemented carbide, cermets, ceramics and similar materials with good abrasive wear resistance starting from a slurry, wherein the slurry is introduced into a drop forming device including at least one essentially horizontal oriented rotating drop forming disk (12), from which the drops are slung out to solidify by centrifugal force. According to the invention the slurry is ejected from a discharge opening (21) on the drop former in the form of a jet such that it hits a first obliquely downward and inwardly directed surface (22) whereby the speed of rotation of the disk is chosen such that the jet of liquid is forced upwards over the first surface as well as over to another connected horizontal surface (23) and thereafter is ejected as a split jet against a second obliquely downwards-outwards directed surface (25) such that the slurry is accelerated to the speed of the drop forming disk (12) and then is led over a third surface (26) obliquely directed outwards, from where the drops are then caused to detach themselves and fall down, thus forming a powder.

摘要： A spray pyrolysis method for producing pure metal and/or metal oxide particles uses a mixture of a carrier gas and a solution of a metal salt precursor, water and a co-solvent reducing agent. The metal salt precursors preferably comprise metals from the group consisting of Fe, Co, Ni, Cu, Zn, Pd, Ag and Au, whereas the salt anions preferably comprise nitrates, acetates, oxalates and chlorides. The co-solvents are those that act as a reducing agent, are vaporizable, are inert with respect to the carrier gas, and are hydrophilic, such as alcohols, in particular, low-carbon numbered alcohols such as methanol or ethanol.
