Question:
Corundum is __________ mineral of aluminium.
Corundum is __________ mineral of aluminium.
Show Hint
Corundum = Al$_2$O$_3$ → oxide mineral (also base material for ruby and sapphire).
Updated On: May 1, 2026
- Silicate
- Oxide
- Double salt
- Sulphate
- Nitrate
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Corundum is a naturally occurring crystalline form of aluminium oxide: \[ Al_2O_3 \]
Step 1: Identify composition
Since it consists of aluminium and oxygen only, it is classified as an oxide mineral. Final Answer: \[ \boxed{(B)} \]
