Question

The Van Arkel method is specifically utilized for the purification of Titanium ($Ti$) and Zirconium ($Zr$). What is the primary reason this highly specialized and expensive method is chosen over standard carbon reduction for these specific metals?

Prashant Kotian · Accepted Answer

Correct answer: C. Ti and Zr cannot be extracted efficiently via pyrometallurgy because they form very stable carbides at high temperatures. Furthermore, they aggressively absorb and from the air, which ruins their mechanical properties (making them brittle). The Van Arkel method (using in an evacuated vessel) perfectly isolates the metal, completely removing all and traces.
