Description

Verfahren zur Darstellung von Pyrit, insbesondere Detektor-Pyrit In dem Patent 883 745 ist ein Verfahren zur Herstdlllung von Pyrit, insbesondere Detektor-Pyrit, durch Reaktion von Eisen und Schwefeleisenverbindungen mit überschüstsigem Schwefel oberhalb Rotglut beschrieben worden.Process for the representation of pyrite, in particular detector pyrite In the patent 883 745 is a process for the production of pyrite, in particular detector pyrite, by reaction of iron and iron sulphide compounds with excess sulfur has been described above red heat.

In weiterer Ausbildung dieses Verfahrens hat es sich gezeigt, daß bei Ausführung des im Hauptpatent beschriebenen Verfahrens unter Zusatz von Metaldhaloggeniden, die bei Reaktionstemperatur im geschmolzenen Zustand vorliegen, der Pyrit in wohl- . ausgebildeten, hochglänzenden einzelnen Kristallen anfällt, die eine ausgezeichnete Detektorwirkung besitze. Anscheinend findet bei Gegenwart einer flüssigen Phase eine Rekristallisation des Pyrits statt, wobei vorhandene Verunreinigungen von .der Schmelze ,aufgenommen werden, so daß keine Trennungsschichten zwischen einzelnen Kristallen durch Verunreinigungen entstehen und ein Wachstum der kleinen Kristalle zu größeren Kristallen ermöglicht wird.In a further development of this process it has been shown that when carrying out the process described in the main patent with the addition of metal halides, which are in the molten state at the reaction temperature, the pyrite in well- . formed, high-gloss individual crystals accrues, which is an excellent Have detector effect. Apparently takes place in the presence of a liquid phase a recrystallization of the pyrite instead, with existing impurities of .der Melt, so that there are no separating layers between each Crystals are formed by impurities and a growth of small crystals larger crystals is made possible.

Für die Durchführung ges Verfahrens eign.cn sich beson.deis die Chloride und Bromide des Eisens und auch .die Alkalichloride. An Stelle von Eisen-und Eisen-Schwefel-Verbindungen auszugehen, ge- Engt die Pyritsynthese auch unter Verwendung von Eisenoxyden als Ausgangsmaterial, z: B. nach folgendem Reaktionsverlauf 2 Fee 02 -f- r r S -->4 Fe S2 -i- 31 S 02. Bei Ausführung (dieser Reaktion wirkt sich ein Halogenndzusatz besonders günstig aus.The chlorides and bromides of iron and also the alkali chlorides are particularly suitable for carrying out the whole process. Starting from iron and iron-sulfur compounds instead of starting the pyrite synthesis also using iron oxides as starting material, for example according to the following reaction process 2 Fee 02 -f- rr S -> 4 Fe S2 -i- 31 S 02. When this reaction is carried out, the addition of halogen has a particularly favorable effect.

Nach 48 Stunden haben sich etwa 1,5 g Fe S2 wohlausgebildete, glänzende Kristalle gebildet.Execution sbei; s: piele i. 2gFeS in powdered or compact form nvit r g of sulfur with the addition of 2 g of Fecd2 in an evacuated Supremax glass tube heated to 730 ° C. After 48 hours, about 1.5 g of Fe S2 have well formed, shiny crystals formed.
