Evaporation and Diffusion of Mn in Inert Systems

Abstract

This research is aimed to improve our knowledge on the dust formation and clustering in the ferroalloy industry. Specifically, this paper focuses on the evaporation of manganese metal, and how different parameters influence the evaporation rate. Experiments were done with pure manganese metal heated to between 1400 and 1700°C in a pure argon atmosphere, where the change in weight was measured to calculate the loss of manganese over time. A mathematical model was constructed to link theoretical values to the results from the experiments. The high control over the system parameters allowed for the validation, rejection or creation of values and theories used in the model.
