  • CRUCIBLE FOR MELTING SILICON AND RELEASE AGENT USED TO THE SAME
    Publication number: 20090277377
    Abstract: 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 SiOXNY 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.
