Studies on slag refining and directional solidification in the purification of silicon
, 1987 A new silica based slag has been developed in slag refining to reduce the aluminium concentration in solvent refined silicon. Besides aluminium, elements like Fe, V, Zr, P, etc. are reduced significantly.

Slag-steel Reactions in the Refining of Advanced High-Strength Steel
ISIJ InternationalAdvanced high-strength steels (AHSS) typically have much higher aluminium concentrations (by an order of magnitude or more) than conventional low-carbon aluminium-killed steels. The resulting lower oxygen activity at the steel-slag interface changes the kinetics and thermodynamics of steel-slag reactions.
