Description

Synthese hexagonaler Mineralien der Nephelingruppe Die bisherige synthetische Herstellung einiger der in der Natur vorkommenden Nepheline erfolgte sowohl durch Schmelzfluß der Ausgangsstoffe, wie z. B. Soda mit Tonerdesilikaten im stöchiometrischenVerhältnisNag 0.A12 03 . 2 Si 02, als auch auf nassemWege. Die sich aus den Schmelzen oder den wäßrigen Lösungen ausscheidenden hexagonalen oder triklinen Kristalle konnten praktisch nicht verwendet werden. Nach dem Verfahren des Patents 486 2,18 werden Plagioklase dadurch auf synthetischem Wege erhalten, daß man die Oxyde von Magnesium, Calcium, Strontium, Barium, Zink und zweiwertigem Eisen bzw. Verbindungen dieser für sich oder in Mischung miteinander in dem für Plagioklase entsprechenden oder angrenzenden Mengenverhältnis unterhalb der Schmelztemperatur mit Tonerde und Kieselsäure oder geeigneten Tonerde- und Kieselsäureverbindungen zur Reaktion bringt. Benutzt man dieses Verfahren unter gleichzeitiger Verwendung von katalytisch wirkenden Titanverbindungen, so bilden sich teilweise oder ganz an Stelle der Plagioklase hexagonale Mineralien der Nephelingruppe. Überraschenderweise hat sich nun gezeigt, daß Mineralien gleicher chemischerZusammensetzung vom Typ R0 -A1203 . zSi02 chemisch und mechanisch eine viel größere Widerstandsfähigkeit haben, wenn sie hexagonal kristallisieren. Dadurch gewinnt das Verfahren des Hauptpatents zur Synthese der Plagioklase eine gesteigerte industrielle Bedeutung.Synthesis of hexagonal minerals of the nepheline group The previous synthetic one Manufacture of some of the naturally occurring nephelins was done by both Melt flow of the starting materials, such as. B. Soda with alumina silicates in the stoichiometric ratioNag 0.A12 03. 2 Si 02, as well as on wet roads. Those resulting from the melts or the Hexagonal or triclinic crystals precipitating from aqueous solutions could be practical Not used. According to the method of patent 486 2.18 plagioclase obtained by synthetic means, that the oxides of magnesium, calcium, Strontium, barium, zinc and bivalent iron or compounds of these for themselves or as a mixture with one another in the one corresponding or adjacent for plagioclase Quantity ratio below the melting temperature with alumina and silica or brings suitable alumina and silica compounds to the reaction. One uses this process with the simultaneous use of catalytically active titanium compounds, Thus, in place of the plagioclase, hexagonal minerals are partially or completely formed of the nepheline group. Surprisingly, it has now been shown that minerals are the same chemical composition of type R0 -A1203. zSi02 chemically and mechanically one have much greater resilience when they crystallize hexagonally. Through this the process of the main patent for the synthesis of plagioclase gains an enhanced one industrial importance.
