In a crucible for holding a molten semiconductor material and producing an ingot, a crucible and a method for improving the take-out characteristics for taking out the solidified ingot from the crucible without causing cracks during and after solidification are provided. . A body having a bottom and a sidewall extending upwardly from the bottom, the bottom and the sidewall defining a cavity for holding the semiconductor material, and the sidewall being an inner surface and an outer surface. And a coating on a part of the inner surface of the side wall, the coating comprising silicon nitride and yttria as a sintering agent. [Selection] Figure 1 |
