Question:
Which of the following is neutral refractories material?
Which of the following is neutral refractories material?
Show Hint
Neutral refractories: SiC, Al\(_2\)O\(_3\), graphite → resist both acids and bases.
Updated On: Apr 15, 2026
- SiO\(_2\)
- MgO
- CaO
- SiC
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Refractories are classified as acidic, basic, or neutral.
Step 1: Identify each option.
• SiO\(_2\) → Acidic refractory
• MgO → Basic refractory
• CaO → Basic refractory
• SiC → Neutral refractory
Step 2: Conclusion. Only SiC resists both acids and bases.
