Q. |
Which of the following statements is appropriate for Stockbarger method? |
A. | solidification is achieved by passing the melt through a concentration gradient |
B. | solidification is achieved by passing the melt through a temperature gradient |
C. | liquefaction is achieved by passing the melt through a concentration gradient |
D. | liquefaction is achieved by passing the melt through a temperature gradient |
Answer» B. solidification is achieved by passing the melt through a temperature gradient | |
Explanation: stockbarger method is based on solidification of stoichiometric melt but in these, oriented solidification of the melt is achieved by effectively passing the melt through a temperature gradient such that crystallization occurs at the cooler end. thus this method is achieved by arranging for a relative displacement of the melt and a temperature gradient. |
