GEBRÜDER SIEMENS & CO. in CHARLOTTENBURG. Verfahren zur Herstellung von geformten festen Körpern aus Siliziumkarbid.BROTHERS SIEMENS & CO. in CHARLOTTENBURG. Process for the production of shaped solid bodies from silicon carbide.
Zusatz zum Patente 176001 vom 4. Januar 1905.Addendum to patent 176001 of January 4, 1905.
Patentiert im Deutschen Reiche vom 18. April 1905 ab. Längste Dauer: 3. Januar 1920.Patented in the German Empire on April 18, 1905. Longest duration: January 3, 1920.
Gemäß vorliegender Erfindung wird das inAccording to the present invention, the
dem Patent 176001 beschriebene Verfahren derart ausgeführt, daß in den Ausgangsmate-the method described in patent 176001 designed in such a way that in the starting material
: rialien außer freiem Silizium noch Kohlenstoff in solcher Menge enthalten ist, wie es durch die Formel C2Si2N verlangt wird.: In addition to free silicon, materials contain carbon in the amount required by the formula C 2 Si 2 N.
Der fertige Körper besteht dann aus einer sehr festen und gut leitenden .Masse, die der Hauptsache nach nur aus der chemischen Verbindung C2Si2N besteht.The finished body then consists of a very solid and highly conductive mass, which mainly consists only of the chemical compound C 2 Si 2 N.
Der Kohlenstoff braucht dabei keineswegs in freier Form verwendet zu werden, er kann vielmehr in Gestalt eines verkohlbaren Bindemittels oder zum Teil auch, an Silizium gebunden verwendet werden.The carbon does not need to be used in free form, it can rather, in the form of a carbonizable binder or, in part, also bonded to silicon be used.
Die Grundmasse wird im übrigen in ganz derselben Weise, wie es im Hauptpatent beschrieben
ist, geformt; die geformten Körper werden in Brennofen gebracht und in einer
stickstoffhaltigen Atmosphäre so lange erhitzt, bis die vollständige
CtSitN erfolgt ist.The basic mass is otherwise shaped in exactly the same way as described in the main patent; the shaped bodies are placed in a kiln and heated in a nitrogenous atmosphere until they are complete
C t Si t N has occurred.
