Which of the following statements relating to the sintering of ceramics are false? 1. The driving force for sintering is the reduction of internal interface energy. 2. The source of mass transport at coarsening stage is mainly surface. 3. Sintering involves heating the ceramic to above its melting point. 4. The larger the particle size, the higher the sintering rate would be. 5. Lower temperatures promote diffusion of atoms and mass transport. 2, 4 and 5 1, 2 and 3 1, 3 and 4 1, 2 and 5 3, 4 and 5
