Apparatus for reducing a particle size of a precursor powder material by fluid energy impact according to one embodiment of the invention may include a housing defining an interior milling cavity therein having a peripheral wall. A powder feed inlet operatively associated with the housing introduces the precursor powder material into the interior milling cavity. A feed gas inlet operatively associated with the powder feed inlet introduces a feed gas into the interior milling cavity. A product discharge outlet operatively associated with the housing removes a milled powder product from the interior milling cavity. An oil injection nozzle assembly operatively associated with the product discharge outlet injects oil into a particle-laden product stream from the product discharge outlet.

Apparatus for producing molybdenum disulfide powders

A method of producing powder product includes the steps of: Feeding a precursor powder material into a jet mill; feeding a gas into the jet mill to initiate a jet milling operation to produce size-reduced particles; and coating size-reduced particles with oil so that newly exposed surfaces of size-reduced particles are coated with oil, wherein the coating step includes one or more of a post-milling oil injection process and a pre-milling oil injection process.

Methods of producing molybdenum disulfide powders

A metal article formed by compacting a sodium/molybdenum composite metal powder under sufficient pressure to form a preformed article; placing the preformed article in a sealed container; raising the temperature of the sealed container to a temperature that is lower than a sintering temperature of molybdenum; and subjecting the sealed container to an isostatic pressure for a time sufficient to increase the density of the metal article to at least about 90% of theoretical density.

Sodium / molybdenum metal articles and powder compacts

A molybdenum disulfide powder product produced by jet milling a molybdenum disulfide precursor material and substantially continuously combining newly sized-reduced particles with oil to produce said molybdenum disulfide powder product, said molybdenum disulfide powder product having a D50 particle size of less than 4 &#x3bc;m and an acid number that is less than about 0.5 mg KOH/g. A method for producing powder product includes the steps of: Providing a supply of a precursor powder material; accelerating particles of the precursor powder material by combining them with a flow of gas; confining the accelerated particles in a milling chamber so that they collide with one another to effect a size reduction; and coating newly exposed surfaces of size-reduced particles with oil.

A method for producing a metal article according to one embodiment may include: Providing a supply of a sodium/molybdenum composite metal powder; compacting the sodium/molybdenum composite metal powder under sufficient pressure to form a preformed article; placing the preformed article in a sealed container; raising the temperature of the sealed container to a temperature that is lower than a sintering temperature of molybdenum; and subjecting the sealed container to an isostatic pressure for a time sufficient to increase the density of the article to at least about 90% of theoretical density.

Methods for producing sodium/molybdenum power compacts

Apparatus for producing nano-particles includes a furnace defining a vapor region therein. A precipitation conduit having an inlet end and an outlet end is positioned with respect to the furnace so that the inlet end is open to the vapor region. A quench fluid supply apparatus supplies quench fluid in a gas state and quench fluid in a liquid state. A quench fluid port positioned within the precipitation conduit is fluidically connected to the quench fluid supply apparatus so that an inlet to the quench fluid port receives quench fluid in the gas state and quench fluid in the liquid state. The quench fluid port provides a quench fluid stream to the precipitation conduit to precipitate nano-particles within the precipitation conduit. A product collection apparatus connected to the outlet end of the precipitation conduit collects nano-particles produced within the precipitation conduit.

Method for producing nano-particles of molybdenum oxide

An isomer of ammonium octamolybdate (&ldquo;AOM&rdquo;) and method for producing the same. A new AOM isomer (&ldquo;X-AOM&rdquo;) is described which is characterized by a distinctive Raman spectral profile compared with other AOM isomers including &agr; and &bgr;-AOM. To produce the novel isomer, ammonium dimolybdate (&ldquo;ADM&rdquo;) is combined with molybdenum trioxide (MoO,) and water to yield a mixture. When mixing these materials, optimum results are achieved if at least one of the foregoing molybdenum-containing reagents is added in a gradual, non-instantaneous manner so that the selected reagent is not added to the mixture in a single large mass. This gradual delivery procedure, along with a carefully controlled prolonged heating stage (e.g. in excess of 3 hours) contributes to a maximum yield of high purity X-AOM.

A novel isomer of ammonium octamolybdate ('AOM') and method for producing the same. A new AOM isomer ('X-AOM') is described which is characterized by a distinctive Raman spectral profile compared with other AOM isomers including .alpha. and .beta.-AOM. To produce the novel isomer, ammonium dimolybdate ('ADM') is combined with molybdenum trioxide (MoO.sub.3) and water to yield a mixture. When mixing these materials, optimum results are achieved if at least one of the foregoing molybdenum-containing reagents is added in a gradual, non-instantaneous manner so that the selected reagent is not added to the mixture in a single large mass. This gradual delivery procedure, along with a carefully controlled prolonged heating stage (e.g. in excess of 3 hours) contributes to a maximum yield of high purity X-AOM.
