   Man hat bereits vorgeschlagen, Eisensilizide als Material für die Herstellung   säure-   widerstehender Gefässe zu verwenden; da diese Eisensilizide nur im Hochofen hergestellt 
 EMI1.3 
 so war der Widerstand dieser Materialien gegen Säuren, insbesondere gegen Chlorwasserstoffsäuro nicht hinreichend. 



   Nach vorliegender Erfindung hingegen sollen Metallsilizide als Material für den angegebenen Zweck dienen, welche sich gegenüber den bekannten Ferrosiliziden dadurch unterscheiden, dass sie : 1. einen Gehalt an Silizium zwischen 15 und 20% und selbst 
 EMI1.4 
 Metalle, wie Mangan, Nickel, Blei etc. enthalten, von welchen Metallen stets eines vorherrscht ; 3. dass diese Silizide nicht im Hochofen hergestellt sind. 



     Der Zusatz von anderen Metallen zum Eisen   ist nicht ein   zuf : illiger,   sondern ein wohlerwogener und bezweckt die Eigenschaft des blossen   Fprrosiltzides   in dem Sinne zu verbessern, dass die erhaltene Legierung sich in Formen giessen, leicht weiter bearbeiten lässt, ohne dass ein Splittern oder Schwinden des   Gussstückes   zu befürchten wäre. 



   Die zusammengesetzten Metallsilizide eignen sich ganz vorzüglich zur Herstellung von Apparaten zur Destillation oder zum Abdampfen von schwefelsäure, wie letztere ans den Bleikammern   gewonnen   wird, um sie in diesen   Gefiissen   in konzentrierter Säure von z. B. 66  Bé. überzuführen. Die Form solcher Apparate kann eine beliebige sein und das Anheizen   dersolhen   kann je nach Erfordernis direkt oder indirekt erfolgen, um die bestmögliche Ausbeute mit diesen Apparaten zu erzielen.

   It has already been proposed to use iron silicides as a material for the manufacture of acid-resistant vessels; because these iron silicides are only produced in the blast furnace
 EMI1.3
 thus the resistance of these materials to acids, especially to hydrochloric acid, was insufficient.



   According to the present invention, however, metal silicides are to serve as material for the stated purpose, which differ from the known ferro-silicides in that they: 1. A silicon content between 15 and 20% and themselves
 EMI1.4
 Contain metals such as manganese, nickel, lead, etc., of which metals always one predominates; 3. That these silicides are not made in a blast furnace.



     The addition of other metals to iron is not accidental, but rather a well-considered one and aims to improve the property of the mere Fprrosilzide in the sense that the alloy obtained can be poured into molds, easily processed further without splintering or shrinking of the casting would be feared.



   The composite metal silicides are particularly suitable for the production of apparatus for distillation or for the evaporation of sulfuric acid, such as the latter is obtained in the lead chambers, in order to dissolve it in concentrated acid of e.g. B. 66 Bé. convict. The shape of such apparatus can be any, and the heating of the solhen can be carried out directly or indirectly as required in order to achieve the best possible yield with these apparatuses.
