| 11. | ZrB 2 parts are usually densification during sintering.
|
| 12. | This is due to material densification and a reduction in grain size upon processing.
|
| 13. | This enhances grain boundary diffusion and migration as well as densification of the material.
|
| 14. | Densification is the act of reducing porosity in a sample thereby making it more dense.
|
| 15. | Densification of consolidated powder bodies continues to be achieved predominantly by ( pressureless ) sintering.
|
| 16. | Densification requires constant capillary pressure where just solution-precipitation material transfer would not produce densification.
|
| 17. | Densification requires constant capillary pressure where just solution-precipitation material transfer would not produce densification.
|
| 18. | Ten others employ the post-densification criteria, and finally two more experiment with both.
|
| 19. | Densification is only achieved at temperatures above 1800 �C once grain boundary diffusion mechanisms become active.
|
| 20. | Temperature dependence for densification controls the process because at higher temperatures viscosity decreases and increases liquid content.
