Definitions
- the invention relates to a method for separating molten metals, the metal melts being treated with metal hydrides become.
- a first embodiment of the present invention exists thus in a process for the separation of metal melts II.
- Main group and sub-groups including of their alloys which is characterized in that the Metals or alloys with a metal hydride in one Melt converts.
- these metals are therefore selected from Non-ferrous and non-precious metals, especially selected made of magnesium, calcium, aluminum, silicon, titanium or Zinc and their alloys. If in the sense of the present Invention the term alloy is used, so is this to understand that this at least 30 wt .-% of mentioned metal included.
- Another preferred embodiment of the present invention consists in using metals or metal alloys one of the metal hydrides to be separated.
- metals or metal alloys For separation of magnesium, for example, it is particularly special Advantage of using magnesium hydride.
- magnesium hydride In an analogous way of course, the use of mixed metal hydrides the implementation of alloys possible. In the same way it is but also possible through a special selection of the metal hydride or the metal hydrides deliberately new material components in to introduce the metal alloy.
- the molar ratio from metal including alloys to metal hydride in the range from 1 to 0.0001 to 1 to 100, preferably in the range of 1 in 0.001 to 1 in 0.01, especially in the range of 1 in 0.005 to 1 in 0.03 is set.
- This area is special prefers. Both play within the aforementioned areas economic considerations play a special role as well the possibility of repeating the treatment or implementation several times.
- impurities especially volatile metal hydride to separate forming impurities from a metal.
- the metals or alloys become molten treated with the metal hydrides.
- Advantageously get the hydrides are used, the metals of which are also used as alloy components act in the metal matrix.
- a powdery Al-Mg alloy is applied with a small amount of autocatalytically produced magnesium hydride (TEGO-Magnan®) and heats this mixture in a muffle to about 1000 ° C, so after cooling the Reaction mixture, the solidified metal obtained is light silver shiny outer and inner surfaces that look more ordinary Do not start air even after months of storage.
- TEGO-Magnan® autocatalytically produced magnesium hydride
- zinc Electrode zinc
- a steel capsule was filled with a mixture consisting of 500 g of a 99.5% by weight magnesium powder and 10 g of a 95% by weight autocatalytically produced magnesium hydride (Tego Magnan®), charged and in an inerted induction furnace heated to 750 ° C. The temperature was held for about 3 minutes; then the reaction mixture was cooled. Was received a regulus crisscrossed by light silvery cavities, which even after 3 months of storage in an ordinary atmosphere neither on these cavity surfaces generated by the process, still inclined to the light silver saw cut surface Tarnishing showed.
- Cat Magnan® autocatalytically produced magnesium hydride
- Example 1 As in Example 1, a steel capsule with a mixture was composed from 700 g of a 99.99% by weight lumpy electrolyte zinc and 14 g of a 95 wt .-% autocatalytically produced Magnesium hydride (Tego Magnan®) loaded and in one inerted induction furnace heated to 550 ° C. After about The reaction mixture was cooled for 10 minutes. Receive became a Zn-Regulus, whose saw cut surface even after months Storage in the atmosphere no start-up behavior showed.
- Cat Magnan® Magnesium hydride
- Elemental analysis proves the separation effect achieved by hydride treatment: sample description % Bi % Cu % Fe % Pb % Sn Zn (Initial state) ⁇ 0.001 0.0018 0.0025 0.0023 0.0015 Zn (after treatment with magnesium hydride) ⁇ 0.001 ⁇ 0.001 0.0011 0.0012 ⁇ 0.001
