State whether the following is true or false.
Applying pressure during sintering allows full density at a lower temperature.

  • A.True only at large scales
  • B.False only at small scales
  • C.True
  • D.False

Answer: C

The external stress supplements the surface energy driving force, so less thermal activation is needed. Lower temperature in turn means less grain growth and a finer final microstructure. Strength and grain size move together in a dense ceramic.
