  PROCEDE DE FABRICATION DE FIL DE GERMANIUM.

  
L'invention concerne un procédé de fabrication de fil de ger-

  
 <EMI ID=1.1> 

  
métaux ne permettent pas d'obtenir du fil de germanium. 

  
Suivant l'invention, on remplit de germanium un tube en verre

  
a. haut point de fusion ou en quartz et on chauffe le tout à une température supérieure au point de fusion du germanium, température à laquelle le quartz ou le verre s'amollit,après quoi on étire jusqu'à obtenir un fil de la longueur désirée et finalement, après refroidissement, on enlève le quartz ou

  
 <EMI ID=2.1> 

  
Le tube peut être rempli de germanium, en poudre ou en particules. On peut aussi verser dans le tube du germanium fondu 

  
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

  
 <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.

  
Après étirage et refroidissement, on peut enlever le quartz par dissolution dans l'acide fluorhydrique.

  
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

  GERMANIUM WIRE MANUFACTURING PROCESS.

  
The invention relates to a method of manufacturing ger-

  
 <EMI ID = 1.1>

  
metals do not make it possible to obtain germanium wire.

  
According to the invention, a glass tube is filled with germanium

  
at. high melting point or quartz and heated to a temperature above the melting point of germanium, temperature at which quartz or glass softens, after which it is stretched until a wire of the desired length is obtained and finally, after cooling, the quartz is removed or

  
 <EMI ID = 2.1>

  
The tube can be filled with germanium, powder or particles. You can also pour molten germanium into the tube

  
By way of example, a powdered germanium is filled over a length of 10 mm., A quartz tube with an internal diameter of 3 mm, and

  
 <EMI ID = 3.1>

  
Preferably, the fusion of germanium is carried out, as is moreover customary in the treatments of this substance, in a vacuum or in an atmosphere of protective gas, for example rare gases, nitrogen of the hydrogen or mixtures of these gases.

  
After stretching and cooling, the quartz can be removed by dissolving in hydrofluoric acid.

  
If it is desired to obtain a material with coarse crystals, the stretched tube can be cooled slowly in the direction of its length, for example, when the heating is carried out in a tube furnace by removing the tube.
