Description

Verfahren zur Herstellung von anorganischen Farbpigmenten Es wurde gefunden, daß man violette Farbpigmente dadurch herstellen kann, daß man Boroxyd, Magnesiumoxyd und Kobaltoxyd bzw. an deren Stelle durch thermische Behandlung die entsprechenden Metalloxyde liefernde Metallverbindungen zusammen einem Glühprozeß unterwirft. Man kann bei der Herstellung dieser Pigmente auch so verfahren, daß man zunächst durch Glühen von beispielsweise Magnesiumsulfat und Boroxyd einen weißen Grundkörper herstellt und diesen Grundkörper nachträglich mit Kobaltsulfat innig vermischt und dann glüht.Process for the production of inorganic color pigments It was found that violet color pigments can be produced by using boron oxide, Magnesium oxide and cobalt oxide or in their place by thermal treatment corresponding metal oxides supplying metal compounds together in an annealing process subject. One can also proceed in the production of these pigments in such a way that one first creates a white one by annealing, for example, magnesium sulphate and boron oxide Base body produces and this base body subsequently intimately with cobalt sulfate mixed and then glows.

Je nach Art und Menge der angewendeten Grundkörper bzw. des Kobaltsalzes erhält man violette Farbpigmente verschiedener Farbnuancen, welche sich durch hervorragende Eigenschaften, insbesondere hinsichtlich Deckkraft, Lichtechtheit, Beständigkeit gegen Temperatur- und Witterungseinflüsse und Zementbeständigkeit auszeichnen. Beispiel Man glüht ein inniges Gemenge von 14,8 Gewichtsteilen Magnesiumsulfat und 11,2 Gewichtsteilen B203 zur Vertreibung des S 03 a Stunden bei etwa looo°. Der erhaltene weiße Grundkörper wird mit 16,8 Gewichtsteilen C0S04 # 7H20. gut gemischt und erneut bei etwa 95o° geglüht. Es entsteht ein schönes, sehr beständiges violettes Pigment von hervorragender Deckfähigkeit.Depending on the type and amount of the base material or cobalt salt used, violet color pigments of various color nuances are obtained, which are characterized by excellent properties, in particular with regard to opacity, lightfastness, resistance to temperature and weathering influences and cement resistance. Example It glows an intimate mixture of 14.8 parts by weight of magnesium sulfate and 1 1.2 parts by weight of B203 to the expulsion of the S 03 a hours at about looo °. The white base body obtained is mixed with 16.8 parts by weight of COSO4 # 7H20. mixed well and annealed again at about 95o °. The result is a beautiful, very persistent violet pigment with excellent hiding power.
