  • Crucible for photovoltaics
    Patent number: 8840861
    Abstract: A method for producing a workpiece comprising a layer of an additive-free silicon nitride includes providing a base body of the workpiece. A layer of a slip comprising a silicon powder is applied to an inside of the base body so as to obtain a coated base body. The coated base body is subjected to a reactive firing under nitrogen so as to convert the silicon powder to the additive-free silicon nitride.
    Type: Grant
