Verfahren zur Herstellung weißer Emaillen unter Verwendung von Metallverbindungen in hydratischer Form als Trübungsmittel.Process for the production of white enamels using metal compounds in hydrate form as an opacifier.
Patentiert im Deutschen Reiche vom 7. Mai 1912 ab.Patented in the German Empire on May 7, 1912.
Gegenstand der Erfindung ist ein Verfahren zur Herstellung weißer Emaillen unter Verwendung von alkalihaltigen Zirkonverbindungen in wasserhaltiger Form. Für die alkalihaltigen Zirkonverbindungen in wasserhaltiger Form ist der günstigste Alkaligehalt mit 2 bis 7 Prozent ermittelt worden. Die Erfindung beruht nun auf der Feststellung, daß der Wassergehalt abhängig ist von dem jeweiligenThe invention relates to a method for producing white enamels using them of alkaline zirconium compounds in water-containing form. For the alkaline Zirconium compounds in water-containing form is the cheapest alkali content with 2 to 7 percent has been determined. The invention is based on the finding that the Water content depends on the particular
ίο Alkaligehalt, und zwar in der Weise, daß bei dem geringeren Alkaligehalt größere Mengen Wasser gebunden erhalten werden müssen als bei dem größeren Alkaligehalt. Demzufolge wird bei den nach den bekannten Verfahren hergestellten alkalihaltigen Zirkonverbindungen in wasserhaltiger Form das Wasser entweder gar nicht oder nur teilweise abgespalten, je nach dem Alkaligehalt, welchen es enthält.ίο Alkali content, in such a way that at the lower alkali content, larger amounts of water must be retained than bound at the higher alkali content. Accordingly, in the known method produced alkaline zirconium compounds in hydrous form the water either not at all or only partially split off, depending on the alkali content it contains.
