Liquid phase sintering is advantageous over solid phase sintering due to ______

Liquid phase sintering is advantageous over solid phase sintering due to ______ Correct Answer Kinetics

Liquid phase sintering promotes enhanced kinetics because of the presence of the liquid phase. The capillary attraction due to wetting allows rapid densification, reduction in interparticle friction leads to a faster rearrangement of particles, and presence of liquid phase aids in material flow and better packing.
