 métaux ne permettent pas d'obtenir du fil de germanium. metals do not provide germanium wire. 

  
 Suivant l'invention, on remplit de germanium un tube en verre According to the invention, germanium filling a glass tube

 Le tube peut être rempli de germanium, en poudre ou en particules. The tube may be filled with germanium powder or particles.  On peut aussi verser dans le tube du germanium fondu We can add in the germanium tube molten 

  
 A titre d'exemple, on remplit de germanium pulvérulent sur une longueur de 10 mm., un tube de quartz à diamètre intérieur de 3 mm, et For example, powdery germanium is filled over a length of 10 mm., A quartz tube with internal diameter of 3 mm, and

  
  <EMI ID=3.1> <EMI ID = 3.1> 

  
 De préférence, la fusion de germanium s'effectue, comme il est d'ailleurs d'usage dans les traitements de cette substance, dans le vide ou dans une atmosphère de gaz protecteur, par exemple des gaz rares, de l'azote de l'hydrogène ou des mélanges de ces gaz. Preferably, germanium melting takes place, as is also customary in the treatment of this substance in a vacuum or in a protective gas atmosphere, for example rare gases, nitrogen of hydrogen or mixtures of these gases.

  
 Après étirage et refroidissement, on peut enlever le quartz par dissolution dans l'acide fluorhydrique. After stretching and cooling the quartz can be removed by dissolving in hydrofluoric acid.

  
 Si l'on désire obtenir une matière à gros cristaux, on peut refroidir lentement dans le sens de sa longueur le tube étiré, par exemple, lorsque le chauffage s'effectue dans un four tubulaire en faisant sortir le If one wishes to obtain a large crystal material may be cooled slowly in the direction of its length the elongated tube, for example, when heating is carried out in a tubular furnace and lead the
