Thermal Analysis of the Fabrication of Magnesium Master Alloys Containing Yttrium and Zinc

Resumo

Differential thermal analysis (DTA) is used to study the processes that occurr upon the interaction of yttrium fluoride with sodium fluoride and potassium chloride, which are used as a flux during metallothermic synthesis of an Mg–Y master alloy. Moreover, to find the laws of magnesium-thermal reduction of yttrium from a salt mixture, thermal analysis of the interaction of salt systems, such as yttrium and sodium fluorides and potassium and sodium chlorides with magnesium and zinc, are performed.
