Crucible for solidifying a silicon ingot
The present invention concerns a crucible for solidifying a silicon ingot from molten silicon, characterized in that it is coated at least partially on the inner surface thereof with an outer layer provided in the form of a stack of laminations, each lamination having a thickness varying from 5 to 150 μm, and being formed from a material obtained by thermal decomposition of polysilazane(s) and/or polysiloxane(s) and wherein inorganic particles are embedded having a size varying from 50 μm to 200 μm. The present invention further concerns a method for preparing such crucibles.
