- Rutile
- Wollastonite
- Cordierite
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Fired whiteware products contain different phases after firing. One of the most important crystalline phases formed during firing is mullite.
Step 1: Whiteware bodies commonly contain clay, feldspar, and quartz.
Step 2: During firing, clay minerals decompose and react to form new high-temperature phases.
Step 3: One important phase formed from alumino-silicate raw materials is mullite. \[ \text{Mullite} = 3Al_2O_3\cdot 2SiO_2 \]
Step 4: Mullite improves:
• mechanical strength,
• thermal stability,
• fired strength,
• resistance to deformation.
Step 5: Therefore, one of the phases present in fired whiteware products is: \[ \boxed{\text{Mullite}} \]
