Background and activities
Ferroalloy-, silicon- and solar grade silicon- production
Merete Tangstad was educated at NTH in 1989 and was also awarded her PhD at this institution. She worked in Elkem and Eramet in the period of 1990-2004 with production of ferromanganese alloys. Since 2004 she has been a professor at NTNU and her main fields are ferralloy production, silicon production and solar grade silicon processes.
