Summary
Selenium traces in valleriite are known, but their actual position in the structure remains to be clarified. This has been attempted in this study, the complete valleriite-selenium valleriite solid solution series (with chalcopyrite and cubanite layers) were sythesized under hydrothermal conditions at 450°C and 1 kb pressure in collapsible gold tubes.
Zusammenfassung
Valleriite mit Selenspuren sind bekannt, aber die Position des Se in der Valleriit-Struktur bedarf noch der Klärung. Dies ist die Fragestellung der folgenden Arbeit. Die komplette Mischkristallreihe Valleriit-Selen-Valleriit wurde untersucht, und zwar sowohl mit Kupferkies als auch mit Cubanitschichten; die Synthese ließ sich unter hydrothermalen Bedingungen bei 450°C und 1 kb Druck in kollabierenden Goldkapseln verwirklichen.
