    摘要： The crucible for melting silicon according to the present invention is a crucible for melting silicon including a crucible main body including a heat-resistant member, and a protective film formed at least on an inner surface of the crucible main body, in which the protective film has a composition of SiO X N Y in which X > 0 and Y > 0. The crucible for melting silicon according to the present invention has excellent releasability to a silicon block, reduces the amount of impurities dissolved in a silicon melt, and can be produced at low cost. Furthermore, the present invention provides a release agent for use in the production of the crucible for melting silicon.

    摘要翻译： 根据本发明的用于熔化硅的坩埚是用于熔化硅的坩埚，其包括包括耐热构件的坩埚主体和至少形成在坩埚主体的内表面上的保护膜，其中保护膜 具有SiO XNY的组成，其中X> 0且Y> 0。根据本发明的用于熔化硅的坩埚对于硅块具有优异的可剥离性，减少了溶解在硅熔体中的杂质的量，并且可以在 低成本。 此外，本发明提供了一种用于生产用于熔化硅的坩埚的脱模剂。
