Ferrosilicon is added as a deoxidant and as an alloying element to steel, that require a special low carbon content. The Low Carbon in Ferrosilicon decreases the electrical conductivity and magnetostriction of electrical steels.
Micro-XRF analysis for metal debris and particle analysis
Fast analysis of microscopic metal particles is an important application for engineering (e.g. engine wear analysis). Micro-XRF scanning and spot analysis of specific fragments identifies their chemical composition.
