Description

Aufschluß von Cyanstickstofftitan Titanverbindungen, insbesondere Titandioxyd und Titanchloride, werden nach verschiedenen Verfahren aus titanhaltigen Erzen gewonnen. Bei der Verhüttung von Eisenerzen, die titanhaltig sind (z. B. in Oberschlesien), geht das Titan in die Hochofenschlacke und reichert sich in einem Teil derselben, in der sogenannten Hochofensau, in Form kupferroter Würfel als Cyanstickstofftitan an.Digestion of cyan nitrogen titanium titanium compounds, in particular Titanium dioxide and titanium chlorides are made from titanium-containing compounds using various methods Ores mined. When smelting iron ores that contain titanium (e.g. in Upper Silesia), the titanium goes into the blast furnace slag and accumulates in one Part of the same, in the so-called blast furnace sow, in the form of copper-red cubes as cyan nitrogen titanium at.

Dieses Cyanstickstofftitan, für das bisher noch keine sichere Formel aufgestellt werden konnte, wurde bisher nicht auf Titan verarbeitet, offenbar deswegen nicht, weil es weder durch Säuren noch durch Laugen noch auf sonstigem Wege nennenswert angegriffen wird. Es gelingt jedoch leicht, dieses Cyanstickstofftitan in Kaliumtitanat überzuführen, wenn man es längere Zeit mit Soda und Pottasche bei höheren Temperaturen (etwa 120a°) schmilzt. Durch Behandlung mit der sonst üblichen Soda- und Pottascheschmelze wird jedoch das Cyanstickstofftitan nicht angegriffen. Nimmt man hierzu aber nur so viel Soda und Pottasche, daß die ganze Masse gerade flüssig werden kann, so erstarrt die Schmelze in Form langer, spießiger Nadeln, die in der Hauptsache aus Alkalititanaten bestehen. Durch nachfolgende Behandlung mit Wasser läßt sich auf diese Weise eine wasserhaltige Titansäure gewinnen, die beim Glühen reines weißes Ti 02 liefert. Durch Behandlung mit starker Säure, z. B. Salzsäure, läßt sich die erhaltene Titansäure in Salze, z. B. Titantetrachlorid, überführen.This cyan nitrogen titanium for which as yet no safe formula could be set up, has not yet been processed on titanium, apparently because of this not because it is not worth mentioning either through acids or alkalis or in any other way is attacked. However, it is easy to convert this cyan nitrogen titanium into potassium titanate Transfer if you have it for a long time with soda and potash at higher temperatures (about 120 °) melts. By treatment with the usual soda and potash melt however, the cyan nitrogen titanium is not attacked. But if you only take it for this so much soda and potash that the whole mass can just become liquid, so solidified the melt in the form of long, narrow needles, which are mainly made of alkali titanates exist. Subsequent treatment with water can be used in this way Obtain hydrous titanic acid which, when annealed, yields pure white Ti 02. By treatment with strong acid, e.g. B. hydrochloric acid, the resulting titanic acid in salts, e.g. B. titanium tetrachloride, transfer.
