| 11. | Polycrystalline silicon can be as much as 99.9999 % pure.
|
| 12. | This is typically referred to in industry as polycrystalline diamond ( PCD ).
|
| 13. | Polycrystalline or crystal powder samples may consist of more than one crystal phase.
|
| 14. | It uses 776, 000 polycrystalline silicon photovoltaic modules.

| 17. | The quartz has 35 % of polycrystalline grains.
|
| 18. | First, in polycrystalline materials, each microscopic grain can act as a photovoltaic.
|
| 19. | Ceramic fibres in CMCs can have a polycrystalline structure, as in conventional ceramics.
|
| 20. | Amorphous powder boron and polycrystalline rhombohedral ?-boron are the most common forms.
