PROBLEM TO BE SOLVED: To provide a crucible capping wherein when a compound semiconductor single crystal is grown by a vertical boat method, the solidified crystal is easily separated from the crucible, and the crucible itself can be reutilized. SOLUTION: In one embodiment, the crucible capping is a crucible capping fitted to the lower part of a crucible in order to grow a single crystal by using a liquid sealing agent by a vertical boat method and has a shape suitable for easy break after the growth of the single crystal. In another embodiment, the crucible capping is a crucible capping fitted to the lower part of a crucible in order to grow a single crystal by using a liquid sealing agent by a vertical boat method and has such a shape that a seed crystal does not reach the lowermost part of the inside of the crucible capping.
