Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Liquid phase sintering involves densification of powder compact in presence of a liquid phase that enhances particle rearrangement and diffusion.
Step 1: Statement-I analysis.
Only a small amount of liquid phase is sufficient; not necessarily "appreciable". Hence statement-I is not strictly required.
Step 2: Statement-II analysis.
Some solubility is necessary for solution-reprecipitation mechanism → TRUE.
Step 3: Statement-III analysis.
Complete wetting is NOT always required; partial wetting can still allow sintering → FALSE. Final Answer: \[ \boxed{\text{Statement-I and Statement-II only}} \]
