| Q. |
Which of the following statements describes best the Bridgman method? |
| A. | melt is outside the temperature furnace, solidification begins at the hotter end |
| B. | melt is inside the temperature furnace, solidification occurs at the cooler end |
| C. | melt is inside the temperature furnace, solidification occurs at the hotter end |
| D. | solidification is achieved by passing the melt through a temperature gradient |
| Answer» B. melt is inside the temperature furnace, solidification occurs at the cooler end | |
| Explanation: in the bridgman method, the melt is inside a temperature gradient furnace and the furnace is gradually cooled so that the solidification begins at the cooler end. in this method, it is again advantageous to use a seed crystal and atmospheric control may be necessary. | |
