Zusammenfassung

Kristallographische Daten der Verbindungen 3 PbO·GeO2, 3 PbO·2 GeO2, PbGe(Ge3O9) und 2 PbO·SiO2 werden aus Einkristallaufnahmen ermittelt. Im Zweistoff GeO2-SiO2 wird die vollständige Mischkristallbildung mit Hilfe des Heißpressens experimentell nachgewiesen. Im Dreistoff PbO-SiO2-GeO2 wird der weitgehende Ersatz von Ge durch Si in den Germanatphasen festgestellt.

Abstract

Crystal data of the compounds 3 PbO·GeO2, 3 PbO·2 GeO2, PbGe(Ge3O9) and 2 PbO·SiO2 were determined through single crystal techniques. In the system GeO2-SiO2 the complete solid solution could be proven experimentally by means of hotpressing techniques. In the ternary system PbO-SiO2-GeO2 the exchange of Ge by Si in the germanate compounds was studied.
