Abstract

Foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av sulfid av sjeldent jordmetall som kjennetegnes ved at et halogenid av sjeldent jordmetall bringes i nærvær med et alkalimetall- eller aluminiumhalogenid og varmes i nærvær av hydrogensulfid ved en temperatur som er tilstrekkelig til å fordampe halogenidene. Mere spesielt er halogenidet klorid, det sjeldne jordmetallet cerium og alkalimetallet natrium.
