So that would happen just through random contact due to convection/induction mixing the melt? This fractionation happens in all kinds of scenarios whether it is a bomb reduction, simple casting where there is just an oxide slag, etc. The Th tends to concentrate on just about everything BUT the...
What happens to one of the components when it is at VERY low concentration in a two component alloy? My problem: Uranium decays to thorium. The thorium isotopes it decays to typically have pretty short half lives. During casting, it is well known that thorium fractionates to the slag, crucible...
