The effect of crucible movement in Bridgman-Stockbarger technique

The effect of the crucible movement on the growth of large size alkali halide crystals effected in a ceramic crucible by B‐S technique is investigated. From the studies carried out it follows that the crucible movement adversely affects the thermal conditions in the furnace resulting in a defective growth. To circumvent the problems faced suitable modification of the conventional B‐S technique yielding good crystals is suggested.
