Infolge des langsamen Erkaltens wird die Masse kristallinisch und porös, wodurch ihre ohnedies hygroskopische Beschaffenheit noch vermehrt wird, so dass das Material selbst   wahrend des Zerkieinerns   und Packens leicht Feuchtigkeit aus der Luft aufnimmt und Gas entwickelt, das verloren geht oder in den Behältern, in denen es verpackt wird und aus denen die Beleuchtungsanlagen gespeist werden, gefährlich wirkt.

   Das vorliegende Verfahren besteht darin, dass man die im Schmelzofen geschmolzene gare Masse ans dem Ofen auf abgekühlte Platten oder in dünnen Schichten ablaufen lässt, so dass man das reine, von   halbgaren   Bestandteilen freie Karbid in dichter Beschaffenheit schon nach wenigen Minuten erhält, während das Abkühlen nach früheren Methoden eine Zeit von   10-24   Stunden in Anspruch   nimmt.

  Process for the preparation of carbide.



    Usually the usual mixture of lime or limestone and coal used to make carbide is left after it has been melted in an electric furnace
 EMI1.1
 is surrounded by molten mass in the furnace. As a result of the slow cooling, the mass becomes crystalline and porous, which increases its already hygroscopic nature, so that the material easily absorbs moisture from the air even during crushing and packing and develops gas that is lost or in the containers in which it is packaged and from which the lighting systems are fed has a dangerous effect.



   Furthermore, it is difficult and costly, the attached one is not
 EMI1.2
 The nature of the latter causes, when crushed, a large percentage of fine waste that is not salable.



   The present process consists in letting the fermented mass melted in the melting furnace run off onto cooled plates or in thin layers in the furnace, so that the pure carbide, free of half-cooked components, is obtained in a dense state after a few minutes while cooling takes 10-24 hours according to previous methods.



   The carbide thus obtained does not easily attract moisture during crushing and packing and break larger pieces of waste.
