What does deoxidated mean?
Deoxidated means that oxygen has been removed from a substance, usually through a chemical or metallurgical process. It can function as an adjective, as in “deoxidated copper,” or as a verb form meaning “removed oxygen from.” The word is most closely associated with metallurgy, where unwanted oxygen is removed from molten metals and alloys, and with chemistry more generally. It is less common than deoxidized or deoxygenated, which are often preferred in contemporary technical writing. Deoxidated is nevertheless useful because it is compact and precise: it describes material from which oxygen has been deliberately eliminated rather than merely a substance that happens to contain little oxygen. In technical contexts, the term may imply treatment designed to prevent oxidation, improve material properties, or prepare a substance for further processing. Its specialized character distinguishes it from broader terms such as deoxygenated, which can describe any process or condition involving reduced oxygen levels.
Having had oxygen removed from it, especially through a chemical or metallurgical process.
"The deoxidated copper was tested for electrical conductivity."
Technical and relatively uncommon; deoxidized is more familiar in modern usage.
To remove oxygen from a substance.
"The process deoxidates the metal before it enters the casting stage."
The past participle form deoxidated is used more commonly than the full verb form in many technical descriptions.
Deoxidated is a specialist cousin of the familiar 'deoxygenated': it names the removal of oxygen from a material.

Where does deoxidated come from?
Deoxidated was formed in English by combining the prefix de-, meaning removal or reversal, with oxide and the suffix -ated, meaning made or provided with. Oxide belongs to a family of words built around the Greek root oxys, related to sharpness, and the chemical suffix -ide. The related forms oxidize, oxidation, and deoxidize developed within English scientific terminology to describe processes involving oxygen and its removal.
