Answer» Correct answer is (d) Optical floating zone furnace Explanation: The drop cast ingots are directionally solidified using an optical floating zone furnace, in which radiation is emitted from a xenon lamp and focused on the specimens enclosed in a quartz tube which is basically evacuated first and back filled with the argon gas. And then drop-cast rods are used as the feed material for the performing of other operations. |
