Abstract: The present invention is directed to a method of manufacture of metal or alloy powders that uses liquid phase reduction of a metal halide, or a mixture of metal halides, to produce a metal particle coated in salts produced as a reaction byproduct. The reaction conditions can be chosen to select a range of metal particle sizes, and the salt coating prevents oxidation (or reaction with other atmospheric gases) and permits a range of applications hitherto difficult to achieve using metal powders.

Abstract: Composition for releasing sodium or strontium or both into molten aluminum or aluminum-based alloy. The composition is formed by fusing a mixture containing at least two salts, at least one of the salts having sodium as a cation and/or at least one of the salts having strontium as a cation, at least one of the salts having carbonate as an anion and at least one of the salts having a halide as an anion. The composition may be employed as a modifying flux for altering the microstructure of aluminum and aluminum alloy.

Abstract: The invention relates to a flux salt composition for flux baths which is available for particularly simple regeneration and deferrizing.

Abstract: An apparatus for producing coated metal granules is disclosed. The apparatus includes a source of molten metal, a device for forming droplets of the molten metal, a bed of particles for receiving the droplets and a means for introducing a gas to fluidize the bed, cooling equipment to maintain the bed below the solidus temperature of the metal, and a separator for separating solidified granules of the metal from particles of the bed. This apparatus can produce an alloying additive which comprises magnesium granules 1-10 mm in size, at least partially coated with particles of a chloride salt which are attached to the granules by being physically embedded into a surface of the granules. The salt particles remain unmelted or only partially melted during formation of the additive.

Abstract: A stable aqueous solution comprising a water soluble salt of a magnesium compound, a surfactant and a calcium salt inhibitor is used to reduce deposits in kilns or furnaces used to make iron ore agglomerates, known as pellets, during iron ore calcination.

Abstract: A clean refractory metal sponge fines product is made from refractory metal sponge fines free of refractory metal oxides, carbides, nitrides and binary iron alloys; silicon carbide, oils, greases and organic compounds; salt; dust; dirt; pieces of iron, iron alloy and tungsten carbide; and light contaminants. The sponge fines are vigorously washed and rinsed with a displacement wash to remove the bulk of the wash fluid and subject to a counter-current wash to yield clean refractory metal sponge fines. The clean sponge fines can be pressed into briquettes and sintered at elevated pressures, or mixed with an alkali metal refractory metal halide slat, pressed at elevated pressures into sponge fines/salt briquettes and dried or pressed into briquettes, dried and packaged, or pressed into briquettes and stored wet. The briquettes are non-pyrophoric.

Abstract: A clean refractory metal SWARF particle product is made from refractory metal SWARF. The SWARF particles are produced with coolant at a temperature less than 650.degree. C. to prevent formation of refractory metal oxides and nitrides. The SWARF particles are comminuted to reduce the particle size of the SWARF slivers and to liberate residual coolant The comminuted SWARF slivers are washed with a displacement wash to remove the bulk of the coolant and subject to a counter current wash to remove substantially all of the coolant components to produce to clean SWARF particles. The clean SWARF particles can be pressed into briquettes and sintered at elevated pressures or mixed with an alkali metal refractory metal halide salt, pressed at elevated pressures into SWARF/soft briquettes and dried. The briquettes are non-pyrophoric.

Abstract: Disclosed is an improved flux comprising 32 to 61 wt. % sodium chloride, 2 to 15 wt. % magnesium chloride, 2 to 12 wt. % carbon, the remainder potassium chloride.
