Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Different ceramic and glaze materials melt at different temperatures depending upon their chemical composition.
•
Step 1:
Borax acts as a strong flux and melts at relatively low temperature.
•
Step 2:
Copper carbonate decomposes and melts after borax.
•
Step 3:
Calcium carbonate requires higher temperature decomposition.
•
Step 4:
Dolomite melts at a higher temperature compared to calcium carbonate.
•
Step 5:
Alumina has extremely high refractory properties and melts at the highest temperature among the given materials. \[ \boxed{\text{(4) D, E, B, A, C}} \]
