Description

Anwendung von Erdalkaliverbindungen als Mineralisatoren Unter »Mineralisatorene versteht man Verbindungen, welche die Fähigkeit haben, bestimmte Kristallgitter für den Eintritt einer oder mehrerer weiterer Komponenten zu öffnen.Use of alkaline earth compounds as mineralizers one understands connections, which have the ability to form certain crystal lattices open for the entry of one or more additional components.

Es ist bekannt, Alkaliverbindungen als Mineralisatoren für verschiedene Zwecke einzusetzen. So werden z. B. nach dem Patent 849 074 Natrium-, Lithium-oder Kaliumoxide, -hydroxide, -carbonate oder -fluoride verwendet, um das Wirtsgitter Zirkoniumsilikat aus den Komponenten Zirkoniumdioxyd und Siliciumdioxid zu bilden.It is known to act as mineralizers for various alkali compounds Purposes. So z. B. according to the patent 849 074 sodium, lithium or Potassium oxides, hydroxides, carbonates or fluorides are used to form the host lattice To form zirconium silicate from the components zirconium dioxide and silicon dioxide.

Eine derartige Umsetzung erfolgt bei Temperaturen, die wesentlich niedriger sind als die bei der Umsetzung der beiden Komponenten ohne Zusatz von Alkaliverbindungen. So würden sich Zirkoniumdioxyd und Siliciumdioxid in Abwesenheit eines Mineralisators bei Temperaturen erst oberhalb 1400°C zu Zirkonsilikat umsetzen, während diese Reaktion in Gegenwart eines Mineralisators schon bei etwa 750°C erfolgen kann.Such a reaction takes place at temperatures which are essential are lower than those in the implementation of the two components without the addition of Alkali compounds. Thus, zirconia and silica would be absent convert a mineralizer to zirconium silicate at temperatures above 1400 ° C, while this reaction takes place in the presence of a mineralizer at around 750 ° C can.

Nach Patent 849 074 bewirken die Alkaliverbindungen gleichzeitig den Einbau eines Chromophors in das entstandene Wirtsgitter, nämlich Vanadin.According to patent 849 074, the alkali compounds simultaneously cause the Incorporation of a chromophore into the resulting host lattice, namely vanadium.

Nach dem belgischen Patent 637 073 werden neben Alkali- auch Erdalkaliverbindungen als Mineralisatoren verwendet. Sie bewirken hier lediglich den Einbau des Chromophors Mns+ in das Wirtsgitter A1203.According to the Belgian patent 637 073, alkali and alkaline earth compounds are used used as mineralizers. They only cause the incorporation of the chromophore here Mns + into the host lattice A1203.

Es wurde nun gefunden, daß Erdalkaliverbindungen in einem keramischen System als Mineralisatoren eingesetzt werden können, um die Bildung eines Wirtsgitters bei niedrigen Temperaturen herbeizuführen und gleichzeitig den Einbau eines Chromophors zu ermöglichen.It has now been found that alkaline earth compounds in a ceramic System can be used as mineralizers to prevent the formation of a host lattice to bring about at low temperatures and at the same time the incorporation of a chromophore to enable.

Vorzugsweise werden Erdalkalihalogenide verwendet, am besten Mischungen verschiedener Erdalkalihalogenide, z. B. Magnesiumfluorid und Bariumfluorid. Besonders wirksam erweisen sich Schmelzen oder Sinterprodukte zweier oder mehrerer Erdalkalihalogenide.Alkaline earth metal halides are preferably used, preferably mixtures various alkaline earth halides, e.g. B. magnesium fluoride and barium fluoride. Particularly Melts or sintered products of two or more alkaline earth metal halides have proven to be effective.

Die folgenden Beispiele sollen dem besseren Verständnis des Erfindungsgedankens dienen. Beispiel 1 25,0 g Zr02 werden mit 12,9 g Si02 gemischt; als Mineralisator werden 8,1 g einer Mischung von 3,48 g BaF2 mit 1,38 g CaF2 und 3,24 g MgF2 zugesetzt. Bei einer Calcinierungstemperatur von 800'C bildet sich, wie röntgenographisch nachgewiesen werden konnte, die Verbindung ZrSi04.The following examples are intended to provide a better understanding of the concept of the invention. Example 1 25.0 g of ZrO2 are mixed with 12.9 g of SiO2; 8.1 g of a mixture of 3.48 g BaF2 with 1.38 g CaF2 and 3.24 g MgF2 are added as a mineralizer. At a calcination temperature of 800 ° C , the compound ZrSi04 is formed, as has been shown by X-ray analysis.

Beispiel 2 bis 6 Zu einer Mischung von 25,0 g Zr02 und 12,9 g Si02 werden ein Chromophor und Erdalkaliverbindungen als Mineralisatoren zugesetzt. Als Chromophor wird Fe203 verwendet.

Bei den Beispielen 2 bis 10 handelt- es sieh um die Anwendung der Erdalkaliverbindungen als Minerahsatoren bei der Herstellung von keramischen Farbkörpern. Alle diese Farbkörper weisen eine gute Farbintensität auf.In Examples 2 to 10, see the application of the Alkaline earth compounds as minerals in the manufacture of ceramic pigments. All of these color bodies have good color intensity.

In allen diesen Fällen führten die als Mineralisator angewandten Erdalkaliverbindungen zu dem gewünschten Erfolg. Bei der Anwendung der Erdalkaliverbindungen erweist es sich außerdem als vorteilhaft; daß man diese - im Gegensatz zu den Alkaliverbindungen - nicht durch Auswaschen entfernen muß.In all of these cases the alkaline earth compounds used as mineralizers led to the desired success. When using the alkaline earth compounds it proves also proven to be beneficial; that one - in contrast to the alkali compounds - does not have to be removed by washing.
