Definitions

  • This curve s When the temperature is higher or lower than 2 , that is, on the lower right side of the curve s () 2 , only titanium Ti (S) can be present in the solid phase, and TiCI 2 (S) is present in the solid phase. Or that TiGI 3 (S) cannot exist.
  • the curve S 02 O Li also low temperature side or high pressure side, i.e. the curve s. If it is located on the upper left side, it means that titanium Ti (S) cannot exist in the solid phase.
  • the lower titanium chloride deposited on the inner wall of the separation chamber 6 is continuously scraped off by the scraper 17 and falls into the lower pyrolysis chamber 3.
  • the electric furnace 38 is placed in the center of the reaction tube 31 because, for example, low-grade titanium chloride clogged in the left purification chamber 36 is pyrolyzed at the electric furnace 38 position on the left side. This is because the lower titanium chloride generated along with the solidification deposits on the purified titanium in the right purification chamber 37, and if the electric furnace 38 is placed at the center of the reaction tube 3 3, this lower titanium chloride will be located at both ends of the furnace. Solidified around the left and right production chambers 33, 34, and the purified titanium in the left and right purification chambers 36, 37 is protected from contamination with low-grade titanium chloride.
  • the electric furnace 8 of this example is a temperature control mechanism, and is configured to surround the reaction vessel 1. In the electric furnace 8, the temperature and the temperature distribution of the production chamber 2, the separation chamber 6, and the thermal decomposition chamber 3 are adjusted.
  • the electric furnace 8 is divided into at least three upper and lower stages, and each section can independently adjust the temperature and the temperature distribution arbitrarily.
  • the supply amount of titanium tetrachloride in the first production reaction was 60.0 (moI), that is, 11.4 (Kg). This is because titanium tetrachloride vapor at a flow rate of 30 (moI / Hr.) Was supplied for about 2 hours.
  • the emission amount of titanium tetrachloride was 23.8 (moI), that is, 4.52 (Kg). After the discharged titanium tetrachloride vapor is liquefied by the condenser, it is stored as liquid titanium tetrachloride in the recovery receiver. This is a numerical value obtained by measuring the amount of liquid stored in this recovery receiver. From the above, the titanium tetrachloride emission was 39.7% of the titanium tetrachloride supply. It is probable that the difference between the supply and the discharge, 6 ⁇ 30/0, was consumed in the production of lower titanium chloride.

Abstract

Cette technique de purification de titane par réaction de titane brut comme matière première avec du tétrachlorure de titane (TiCl4) et ce, afin d'obtenir du titane purifié consiste, (a), à faire réagir le titane brut comme matière première avec du TiCl4 afin de produire de la vapeur de chlorure de titane inférieur (TiClx), (b), à précipiter le TiClx solide à partir de la vapeur de TiClx et, (c), de décomposer par voie thermique le TiClx solide afin de produire du titane purifié, le TiClx étant un chlorure de titane inférieur dans lequel x vaut 2 ou 3. La température t1 (°C) et la pression p1 (Torr) auxquelles se réalise la première étape sont, respectivement, de 750 °C ≤ t1 et log (p1) < 20,158-(21859/(t1 + 273)). La pression (p2) et la température (t2) auxquelles se réalise la deuxième étape sont, respectivement, de 0,001 Torr < p2 < 1520 Torr et de 150 °C < t2 < (21859/(20,158 - log (p2)) - 273 °C. La température t3 (°C) et la pression p3 (Torr) auxquelles se réalise la troisième étape sont, respectivement, de 750 °C ≤ t3 et log (p3) < 20,158-(21859/(t3 + 273)).
