摘要： Gas mixtures of SF6 and N2, which have been used, for example, as an insulating filler gas for underground cables, for insulating-gas window panes or as a filler gas for car tires and SF6/air mixtures which have been used as a protective gas when casting magnesium can be separated if they are contacted with hydrophobic zeolites of a certain pore size as selective adsorption agent for sulfur hexafluoride. For a relatively high SF6 concentration, the mixture is preferably first subjected to a membrane separation process and the permeate is contacted with the adsorption agent. The invention also relates to an apparatus for carrying out the process. The process may also be used for separating SF6 from exhaust gases.

摘要： Elemental fluorine is used as etching agent for the manufacture of electronic devices, especially semiconductor devices, micro-electromechanical devices, thin film transistors, flat panel displays and solar panels, and as chamber cleaning agent mainly for plasma-enhanced chemical vapor deposition (PECVD) apparatus. For this purpose, fluorine often is produced on-site. The invention provides a process for the manufacture of electronic devices wherein fluorine is produced on site and is purified from HF by a low temperature treatment. A pressure of between 1.5 and 20 Bars absolute is especially advantageous.

摘要： A method of avoiding generation of waste water while brazing components made of aluminium or an aluminium alloy using a flux, especially a flux composed of an aqueous suspension of potassium fluoroaluminate. Since used suspension is replaced with fresh suspension after a given period of time and the apparatus regularly have to be cleaned, waste water is produced which contains flux, e.g. potassium fluoroaluminate. In the past, such waste water has been discharged into the environment. It has now been discovered that such waste water can be recycled to the brazing process after separation of the flux. In this manner, the production of waste water can be largely avoided. Since surfactants are frequently used, and these are likewise recirculated, a corresponding saving in terms of surfactant is possible. Furthermore, the environment is protected correspondingly.
摘要翻译：一种避免产生废水的方法，同时使用助熔剂特别是由氟铝酸钾的水悬浮液组成的焊剂钎焊铝或铝合金制成的组分。由于在给定的时间段内使用的悬浮液被新鲜的悬浮液代替，并且该装置经常需要清洁，因此产生含有助熔剂的废水，氟铝酸钾过去这种废水已经排入环境。现在已经发现，在分离助熔剂之后，这种废水可以再循环到钎焊过程中。以这种方式，可以大大地避免废水的生产。由于表面活性剂经常被使用，并且它们同样被再循环，因此表面活性剂的相应的节省是可能的。此外，相应地保护环境。

摘要： Mixtures of fluorine and inert gases like nitrogen and/or argon can be used for etching of semiconductors, solar panels and flat panels (TFTs and LCDs), and for cleaning of semiconductor surfaces and plasma chambers. Preferably, fluorine is comprised in an amount of 15 to 25 vol.-% in binary mixtures. The gas mixtures can be used as substitute or drop-in for respective mixtures comprising NF3 and permit a very flexible operation of plasma apparatus. For example, apparatus tuned for NF3/Ar mixtures can be operated without further tuning using fluorine and argon, optionally together with nitrogen. The fluorine content is preferably in the range of 1 to 5 vol.-%, if ternary mixtures of fluorine, nitrogen and argon are used.
