| titleOfInvention | Quartz glass crucible |
| abstract | [Problems to be solved] Provided is a quartz glass crucible having high durability even at a high temperature during a single crystal pull-up step and capable of reducing a generation ratio of pinholes in a silicon single crystal. n [Means to solve the problems] A quartz glass crucible 1 includes: a quartz glass crucible body 10 having a cylindrical side wall portion 10 a , a curved bottom portion 10 b , and a corner portion 10 c which has a larger curvature than that of the bottom portion 10 b and connects the side wall portion 10 a and the bottom portion 10 b to each other; and an inner-surface coating film 13 A which contains a crystallization accelerator and is formed on an inner surface 10 i of the quartz glass crucible body 10 , in which the inner surface 10 i of the quartz glass crucible body 10 is under compressive stress. |
