In the industrial extraction of titanium (the Kroll process), titanium tetrachloride (TiCl4\text{TiCl}_4TiCl4) is reduced by liquid magnesium at temperatures exceeding 800∘C800^\circ\text{C}800∘C inside a steel reactor to produce titanium metal.
Explain why argon, rather than air, is used to provide the atmosphere inside the reactor during this high-temperature extraction process.
