Definitions

  • the greater waste of these materials is that they have become more and more divided by a significant hazard of gas and nitrogen (low consumption), or of low nitrogen consumption.
  • the available material on the USC metal is available and the iron and nitrous metals are W-UP group Per-5, which is available in a separate way. The method of making it is included. Shredding to a dispersion of 0.01-2 mm is less than a single one, containing 30-70 wt. metal ⁇ Y- from the group: aluminum, titanium, zinc, niobium, 0 tantalum, ⁇ ⁇ admir ⁇ , molybdenum, etter lith lithi, or of low nitrogen consumption.
  • the fraction of the base is produced by a liquid mechanical mechanism and is subject to the formation of a base from the metal alloy of the iron group.
  • the content of nitrogen in it was not ⁇ - ⁇ ysh ⁇ 11.9 wt. , so as to take care of a long-lasting, stable condition, there’s only some negligence
  • the described method reveals the best way to save energy, the duration of the process, not to use the available products. It is also slowing down due to the low pressure, which reduces the small increase in the rate of increase in the rate of increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in

  • the material, according to the invention contains aluminum nitride in the amount of 0.4-36 wt. .
  • a convenient type of cooling device can be obtained by any means: shredding, electrolysis, spraying, settling, condensation from a waste gas.
  • Aluminum is a non-ferrous metal; it can be treated with nitrous oxide; The incidence of the inconvenience of the cry does not deteriorate.
  • the ISD ⁇ material is more than 36 wt. There is no complete waste of aluminum 5 ⁇ nitride and no burning. Flame-free aluminum is released when it is consumed, it reduces the risk of impairment of activity for the non-operating environment. 0 Received feedback from the user is subject to the same conditions.
