In the process of synthesizing alloys of Mn and other metals, there are too many losses due to Mn evaporation. Pelletized(cold press) metal nano powder is used for arc melting.
I know that the boiling point of Mn is not relatively high, so it's impossible to completely prevent the loss. However, it's not easy to predict the composition by adding supplement because the amount of loss is too huge.
If Mn loss can be reduced, it will be easier to match the composition through supplement. Would it be helpful to use metal pieces instead of pelletized nanopowder?
Is there anyone else who has a good idea?
It has nothing to do with the boiling point of manganese; the problem is with briquettes.
When an arc is passed through a pressed briquet of fine metallic particles, the particles heat up individually. This causes extremely rapid heating (almost explosion) to very high temperatures and subsequent material losses. It doesn't really matter how high the boiling point of metal is, the particle size is much more important.
For the above-mentioned reason, one should never work with fine-grain powders when melting an arc, but only with solid pieces.
Vadim Verlotski Thank you so much for your answer, I'll try to do arc melting using metal pieces.
