Description

Herstellung von synthetischen gelben Spinellen Es ist bereits vorgeschlagen worden, zur Darstellung künstlicher Spinelle mit lichtgrünem Farbton Spinellmischungen nach Zusatz von Kobalt, Vanadin und Mangan als Farbträger im Knalllgasgebläse zu verschmelzen. Für sich allein reichen- die dort angegebenen Mengen Mangan noch nicht aus, um eine Färbung des Steines hervorzurufen. Andererseits ist bekannt, daß ein Zusatz von Eisen zu synthetischen Spinellgemischen in den erhaltenen Steinen eine rosa Färbung hervorruft.Manufacture of synthetic yellow spinels It has already been proposed for the representation of artificial spinels with a light green shade of spinel mixtures after adding cobalt, vanadium and manganese as color carriers in the oxyhydrogen blower merge. On its own, the quantities of manganese given there are not yet sufficient to cause the stone to color. On the other hand, it is known that a Addition of iron to synthetic spinel mixtures in the stones obtained pink color.

Es wurde nun gefunden, daß synthetische Spinelle von gelber Farbe erhalten werden, wenn als Farbträger Mangan und Eisen gemeinsam verwendet werden. Dies ist um so überraschender, als nach den Regeln der Farbmischung nicht angenommen werden konnte, daß die Kombination von Mangan mit Eisen, von denen der erstere nicht und der zweite rosa färbt, einen gelben Spinell ergeben würden.It has now been found that synthetic spinels are yellow in color can be obtained when manganese and iron are used together as color carriers. This is all the more surprising as it is not assumed according to the rules of color mixing could be that the combination of manganese with iron, of which the former is not and the second turns pink, would make a yellow spinel.

Zu einer Grundmischung von etwa 9o% Tonerde und etwa i o % Magnesia werden q.% Mangan(3)oxyd und i% Eisen gegeben. Die Mischung wird in bekannter Weise nach V-e r n e u i l auf synthetischen Spinell verarbeitet. Mangan und Eisen können als Elemente oder in Form von Verbindungen, am zweckmäßigsten- ,als Oxyde, dem Tonerde-Magnesia-Gemisch zugesetzt werden.To a basic mixture of about 90% clay and about 10% magnesia q.% manganese (3) oxide and i% iron are given. The mixture is made in a known manner processed according to V-e r n e u i l on synthetic spinel. Manganese and iron can as elements or in the form of compounds, most expediently, as oxides, the alumina-magnesia mixture can be added.

Gibt man zu der Ausgangsmischung noch Zinkoxyd (z. B. r bis z%) hinzu, so wird das Schmelzen der Steine erleichtert und der Farbton intensiver, obwohl Zinkoxyd selbst keine Färbung verursacht.If you add zinc oxide (e.g. r to z%) to the starting mixture, so the melting of the stones is made easier and the hue more intense, though Zinc oxide itself does not cause any staining.

Man kann den Rohstoff für diesen gelben Spinell auch zur Abstimmung der Farbtöne (Nuancierung) der bekannten grünen und blauen (durch Chrom, Vanadin und Kobalt gefärbten) Spinelle auf Grundlage von Tonerde-Magnesia-Gemischen verwenden, indem man dem Ausgangsgemisch für die grünen oder blauen Spinelle bestimmte, durch Versuche ermittelte Anteile des Rohstoffgemisches für gelben Spinell zusetzt und die Mischung verarbeitet.You can also vote on the raw material for this yellow spinel the color tones (nuances) of the familiar green and blue (through chrome, vanadium and cobalt-colored) spinels based on alumina-magnesia mixtures, by determining the starting mixture for the green or blue spinels Trials determined proportions of the raw material mixture for yellow spinel adds and processed the mixture.
