Definitions

  • the hydrogenative dewatering method and rotary electrode method are being put to practical use as improved production methods for titanium metal powder.
  • the hydrogenative dewatering method uses sponge titanium, molten titanium or titanium chips generated from cutting/machining as material.
  • the material titanium is heated in a hydrogen atmosphere to cause it to absorb the hydrogen gas and thus become brittle. This brittle titanium is then crushed and heated again in vacuum so that the hydrogen gas will be released and powder formed.
  • molten titanium or titanium melted then forged, rolled or otherwise worked is formed into a round bar to be used as material.
  • This material round bar is turned at high speed in an atmosphere of argon, helium or other inactive gas, while its tip is melted by a heat source such as an arc or plasma-arc torch.
  • the drips of molten metal are then scattered via centrifugal force to produce spherical powder grains.
  • the method proposed by the present invention generates virtually no byproducts or impurities other than the target metal powder. Occurrence of metal oxidation due to heating of material metal is also very small, and since the obtained metal powder has excellent uniformity of granular sphericity and consistency of granule size, the production cost can be reduced significantly.
  • the method also allows for continuous production in addition to batch production, which opens a door to mass-production of metal powder having uniform granule size.
  • purified water such as distilled water is filled into the high-pressure water tank inside the pressure-resistant container for titanium-metal powder production, and material titanium metal such as a titanium metal bar is fed from the material element-metal feeder part and pressurized at high pressure.
  • a mixture gas consisting of hydrogen and oxygen is injected from the nozzle, ignited and let completely bum in the combustion chamber.
  • material titanium is instantly melted in the combustion gas and dispersed in water.
  • very fine titanium grains of micron order are produced and dispersed in powder form.
  • the produced fine titanium powder does not melt or float and precipitates in a short period.
  • mixture gas of hydrogen and oxygen must be precisely controlled to achieve a hydrogen-to-oxygen ratio of 2 to 1. While a mixture gas of hydrogen and oxygen is supplied from commercial gas cylinders, adding a water electrolyzer (C) as an adjunct to produce a mixture gas of hydrogen and oxygen via electrolysis of water will generate completely pure gases to facilitate an optimal, efficient supply of mixture gas.
  • a water electrolyzer C
  • the present invention allows for production of high-purity metal, especially titanium powder, in a very efficient manner.
  • the production method proposed by the present invention achieves pure powder free from byproducts or impurities other than the elemental component, wherein the produced powder offers excellent uniformity of granular sphericity and size and can be produced at significantly less cost. Batch production, continuous production and mass production are also possible.
