Question:
Which is Acid Refractory?
Which is Acid Refractory?
Show Hint
Acid = Silica ($SiO_{2}$); Basic = Magnesite ($MgO$).
Updated On: Jul 4, 2026
- Magnesite
- Chromite
- Dolomite
- Silica
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Refractories are classified as acid, basic, or neutral based on their chemical behavior at high temperatures.
Step 2: Meaning
Acid refractories contain high amounts of silica ($SiO_{2}$). Basic refractories contain $MgO$ or $CaO$.
Step 3: Analysis
Magnesite and Dolomite are basic. Chromite is neutral. Silica bricks are the standard acid refractory.
Step 4: Conclusion
Silica is an acid refractory. Final Answer: (D)
