  • Patent number: 7758839
    Abstract: Method for producing silicon which is suitable as a starting material for producing a silicon melt for the fabrication of silicon blocks or silicon crystals, comprising the following steps: introducing a gaseous mixture of monosilane and hydrogen into a reactor, thermal degrading the gaseous mixture for forming silicon powder, separating the formed silicon powder produced from the gaseous mixture, and mechanical compacting the separated silicon powder with compacting rollers which having a roller jacket consisting of a ceramic material selected from graphite, glass and silicon nitride.

  • Patent number: 7584919
    Abstract: Compacting device for the low-metal compaction of a powder with a casing which at least in part surrounds a working chamber, with a feed arrangement arranged on the casing and feeding a powder, which is to be compacted, into the working chamber, with at least a compacting roller which is rotatably arranged in the working chamber, comprises a roller jacket and, together with an opposing wall, forms a compacting gap for compacting the powder therein, characterised in that the at least one compacting roller consists of ceramic, at least on the roller jacket.
