ABSTRACT:
A crucible for the treatment of molten silicon includes a basic body with a bottom surface and lateral walls defining an inner volume. The basic body comprises at least 65% by weight of silicon carbide, and from 12 to 30% by weight of a constituent selected from silicon oxide or nitride. Moreover, the basic body comprises at least one silicon oxide and/or nitride coating, at least on the surfaces defining the inner volume of the crucible.
