Description

Verfahren zur Herstellung eines synthetischen Spinells in der Farbe der brasilianischen Smaragde Es sind synthetische Korunde bekannt, in denen Magnesium als Hauptfarbträger auftritt. In dem Gegenstand der vorliegenden Erfindung ist aber Magnesium kein färbender Konstituent des erzeugten Steines.Method of making a synthetic spinel in paint of the Brazilian emeralds Synthetic corundums are known in which magnesium occurs as the main color carrier. However, in the subject matter of the present invention Magnesium is not a coloring constituent of the stone produced.

Setzt man einer gewissen Menge Tonerde verhältnismäßig viel Magnesium zu, so entsteht beim Schmelzen der Mischung im Verneuilschen Knallgasbrenner ein Spinell. Mit einem Zusatze von Kobalt, Vanadin und Mangan als Hauptfarbträger läßt sich dieser Spinell, der ein Stein kristallinischer Struktur ist, in der Farbe des brasilianischen Smaragdes, d. h. in dem diesem Stein eigenen lichtgrünen Farbton erzeugen.If you add a relatively high amount of magnesium to a certain amount of clay too, when the mixture melts in the Verneuil oxyhydrogen burner, a Spinel. With an addition of cobalt, vanadium and manganese as the main color carrier This spinel, which is a stone with a crystalline structure, has the color of Brazilian emeralds, d. H. in the light green color that is characteristic of this stone produce.

Das Mengeverhältnis der drei Hauptfarbträger unter sich und zu den Grundstoffen Tonerde und Magnesia kann zur Erzeugung von verschiedenen Abtönungen der lichtgrünen Farbe geändert werden. Ein stärkerer Gehalt an Kobalt gibt z. B. dem Stein einen stärkeren bläulicheren Ton.The ratio of the three main color carriers to each other and to the Basic materials alumina and magnesia can be used to produce various shades the light green color can be changed. A higher content of cobalt gives z. B. the stone a stronger bluish tone.

An Stelle der reinen Metalle können auch geeignete Verdingungen verwendet werden. Als Beispiele seien angeführt: z. Zu ioo g Tonerde werden 1 5 g Magnesia zugesetzt, die man mit o,oro g Kobaltoxydul, o,o8o g Vanadinpentoxyd und 6 g Manganoxvd vermengt und in bekannter Weise schmilzt.Suitable conditions can also be used instead of the pure metals. Examples are: To 100 g of clay, 1 5 g of magnesia are added, which are mixed with 0.06 g cobalt oxide, 0.08 g vanadium pentoxide and 6 g manganese oxide and melted in a known manner.

a. Es werden roog Tonerde, r5 g Magnesia, 0,020 g Kobaltoxy dul, o,o6o g Vanadinpentoxyd und 8 g Manganoxyd gemischt und nach dem bekannten Verfahren im Brenner geschmolzen.a. Roog alumina, 5 g magnesia, 0.020 g cobalt oxide, 0.06 g vanadium pentoxide and 8 g manganese oxide are mixed and melted in the burner using the known method.

3. Wie in den zwei ersten Beispielen erwähnt, mischt man roo @g Tonerde, 15 g Magnesia, o,oro g Kobaltoxyd, o,roo g Vanadinpentoxyd und 8 g Manganoxyd und schmilzt <las Ganze wie oben erwähnt.3. As mentioned in the first two examples, mix roo @g clay, 15 g magnesia, o, oro g cobalt oxide, o, roo g vanadium pentoxide and 8 g manganese oxide and melts <read whole as mentioned above.
