Metallurgical processes remove dissolved oxygen during metal melting using chemical deoxidizers
Metallurgical processes commonly remove dissolved oxygen from molten metals by adding chemical deoxidizers, which form stable oxides and drastically reduce the oxygen content.
The claim is specific, empirical, and well-supported by multiple metallurgical studies showing that chemical deoxidizers are routinely added during melting to reduce dissolved oxygen and remove oxide inclusions.
