Question:
Common impurity metal present in commercial Zirconium metal
Common impurity metal present in commercial Zirconium metal
Show Hint
Zr and Hf are "twins." If you find one, you almost always find the other as an impurity.
Updated On: Jul 4, 2026
- Titanium
- Iron
- Hafnium
- Magnesium
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept Zirconium and hafnium are chemically almost identical due to the lanthanide contraction, making them very difficult to separate.
Step 2: Meaning These two elements always occur together in nature, primarily in the mineral zircon.
Step 3: Analysis While iron or magnesium might be present in trace amounts, hafnium is the most persistent and significant impurity in commercial-grade zirconium.
Step 4: Conclusion For nuclear applications, hafnium must be specifically removed, but it remains the most common impurity in standard commercial zirconium. Final Answer: (C)
