Abstract

In this paper, δ layered sodium disilicate with high framework stability has been synthesized by adding the salts of divalent and trivalent elements. In these salts AlCl3 had the best effect for leaving the phase transformation of δ-Na2Si2O5. XRD, SEM, Ca2+ ion binding capacity and clean experiment were used for measuring their properties. The data proved that Al-δ-Na2Si2O5 had good framework stability. δ phase was still major phase after Al-δ-Na2Si2O5 was treated in hot water (80°C) for 60 minutes. And Ca2+ ion binding capacity may keep at 305 mg CaCO3/g through the treatment. The cleaning experiments showed that Al-δ-Na2Si2O5 had good washing ability.

Kurzfassung

In dieser Arbeit wird die Synthese von δ-Schicht-Natriumdisilikat mit hoher Strukturstabilität durch Zusatz von zwei- und dreiwertigen Salzen beschrieben. Hierbei zeigt AlCl3 die beste Wirkung beim Übergang der Phasentransformation von δ-Na2Si2O5. Zur Bestimmung der Eigenschaften kamen XRD, Rasterelektronenmikroskopie, Ca2+-Ionenbindungsvermögen und Reinigungsversuche zum Einsatz. Die gefundenen Werte belegen, dass Al-δ-Na2Si2O5 eine gute Strukturstabilität besitzt. Nach Einbringen von Al-δ-Na2Si2O5 in heißes Wasser (80°C) für 60 Minuten ist die δ-Phase immer noch die Hauptphase und das Ca2+-Ionenbindungsvermögen wird bei 305 mg CaCO3/g während der Behandlung gehalten. Die Reinigungsversuche zeigen, daß Al-δ-Na2Si2O5 ein gutes Waschvermögen aufweist.
