Abstract
V prispevku obravnavamo analizo vključkov v primarnem aluminiju. Poleg kompleksnih vključkov, pri katerih so komponente s kalcijem topne v vodi, je raziskava odkrila v primarnem aluminiju tudi dvofazne vključke, ki vsebujejo okoli 21,5 at. % molibdena. Molibden je potrdila pazljivejša kemijska analiza nečistoč v primarnem aluminiju, zato domnevamo, da najverjetneje izvira iz glinice. Kljub prizadevanju nam ni uspelo dobiti od proizvajalcev podatkov o vsebnosti molibdena v glinici.

Title:On the source of molybdenum in primary aluminium
Abstract:
The results of a study of the inclusions in primary aluminium are presented. Beside complex inclusions, where components with Ca are soluble in water, the research of primary aluminium also revealed the eutectic-like inclusions with 21,5 at. % molybdenum. Careful chemical analysing of trace elements revealed that molybdenum was already present in primary aluminium, so we suppose the most probable source of molybdenum is alumina. Despite efforts, no data could be obtained from alumina producers about the molybdenum content in alumina.

Keywords:primary aluminium, complex inclusions, alumina, chemical analysis of trace elements
