He also said aluminum nitride may play a role in the wetting of inclusions by molten aluminum. In addition, wet dross indicates a lack of halogens, caused by not adding them or by poor absorption due to slow kinetics. "The removal of inclusions from molten aluminum is essential for the generation of high-quality aluminum products," Martins said.
