Definitions

  • pre-stoichiometric titanium dioxide has high electrical conductivity and can serve as a cathode both for the reduction of titanium oxides to metal and for the removal of dissolved oxygen from it.
  • titanium dioxide at temperatures up to 1400 0 C can be reduced to TiO.
  • aluminum forms solid solutions and intermetallic compounds with titanium with an additional release of Gibbs energy, which helps to restore to the formation of a titanium-aluminum alloy.
  • Berthollet salt is added to the mixture and calcium chloride is used to reduce the melt viscosity.
  • the mixture, stuffed into a graphite chamotte crucible, is ignited with the ignition mixture, and after the reaction spread rapidly throughout the entire volume at the bottom of the crucible, an alloy ingot is obtained that can be easily separated after cooling from the slag.
  • Titanium-aluminum alloys can be used as ligatures in the production of alloys, as well as for obtaining pure titanium from them by electrolytic refining.
  • the combination of aluminothermic reduction of titanium dioxide with subsequent electrolytic refining can be one of the production methods for producing titanium.
  • the equipment material is nickel or Ni - Cu alloys (monel).
  • zirconium powder is not intended for the production of ductile metal, but for direct use in pyrotechnics or, in some cases, in vacuum technology (for example, as a getter) and is not presented to it high purity requirements, it can be obtained by reducing K 2 ZrF 6 sodium similar to the production of tantalum and niobium powders from complex fluoride salts.
  • Potassium fluorozirconate is non-hygroscopic, stable in air.
  • the sodium and potassium fluorides resulting from the reduction are washed off from zirconium with water.
  • Calcium reduction is carried out in sealed apparatus made of heat-resistant steel, where a briquetted mixture of TiO 2 or ZrO 2 with calcium (in the form of chips) is loaded. Distilled calcium must be used.
  • the apparatus is pumped out, filled with argon, heated to 1000 - 1100 0 C and maintained at this temperature for about 1 hour.
  • the reduction product is crushed, treated with a large volume of water [to remove part of CaO in the form of Ca (OH) 2 ], then diluted with HCl, washed with water and dried in vacuum at 40 - 50 ° C.
  • electrolysis is the basis of the electrochemical method of obtaining pure substances. That is, electrochemical oxidation occurs at the anode, where negatively charged ions become neutral and are released from the solution. A reduction reaction occurs at the cathode, where positive ions receive the missing electrons.
  • Briquetting is not required, what is used in ore-thermal furnaces. Briquetting the mixture increases the cost of the process by 27%.
  • metal droplets do not pass through the entire layer of the slag bath in which they could remain, but pass along a short path from the end of the electrode to the molten bath.
  • the highest temperature, and therefore the lowest viscosity of the electrolyte therefore, the resulting metal can easily and without loss to overcome this path.

Abstract

l'invention concerne un procédé de production de métaux chimiquement actifs, ainsi qu'un dispositif pour réaliser ce procédé. Le procédé de l'invention consiste à amener une charge constituée d'un composé métallique réductible et d'un métal réducteur dans la cavité interne d'une électrode-anode graphite. Au cours du chauffage, on effectue d'abord à l'intérieur de l'électrode une réduction métallothermique, et à la sortie de la charge à l'extrémité de l'électrode-anode dans la zone de chauffage de l'arc, la réduction plasmochimique et électrochimique du métal se prolonge de façon à obtenir un bain de métal liquide et de laitier. Le métal est refroidi sur un cristalliseur se présentant sous la forme d'une cathode. Le dispositif comprend un corps, un dispositif mécanique d'amenée de la charge, une trémie et une tubulure. Le dispositif est également pourvu d'un cristalliseur qui est raccordé au pôle négatif et est utilisé comme cathode. Le dispositif est aussi pourvu d'une électrode graphite qui est raccordée au pôle positif et utilisée comme anode comportant un trou central utilisé pour déplacer la charge constituée d'un composé métallique réductible et d'un métal réducteur. Le dispositif mécanique est placé à l'intérieur de la trémie.
