Abstract

An iron sulphide Fe2S3 that showed the Gamma-Al2O3 type of spinel structure was detected by means of electron diffraction. The crystal of this sulphide contained lattice vacancies, and consequently it was chemically more active than Fe3S4. The formula Fe(□1/3 Fe5/3)S4 was associated with the sulphide concerned. The iron sulphides of spinel type that were produced hitherto corresponded to mixed crystals Fe3S4-Fe2S3.

Zusammenfassung

Ein Eisensulfid Fe2S3, das den Gamma-Typ der Spinellstruktur aufwies, ließ sich mit Hilfe der Elektronenbeugung nachweisen. Der Kristall dieses Sulfids enthielt Gitterleerstellen und war infolgedessen chemisch aktiver als Fe3S4. Die Formel Fe(□1/3 Fe5/3)S4 war dem betreffenden Sulfid zuzuordnen. Die bisher dargestellten Eisensulfide vom Spinelltyp entsprachen den Mischkristallen Fe3S4-Fe2S3.
