Abstract:
Control of the flow of granular polysilicon granules is effected by employing an elastomeric pinch sleeve valve. The flow control by this method is especially useful for controlling the flow of silicon seed particles and granular polysilicon product in the fluidized bed method for producing polysilicon. The flow may be stopped without gas leakage, and is suitable for use over long operating campaigns.

Claim (Index 16):
A method for controlling and/or stopping of a flow of particulate polysilicon having a mean particle size of 150 \u03bcm to 10,000 \u03bcm, measured by means of dynamic image analysis according to ISO 13322-2, measurement range: 30 \u03bcm-30 mm, type of analysis: dry measurement of powders and granules,\n Comprising controlling and/or stopping the flow by actuating at least one pinch fitting comprising a pinch-fitting sleeve wherein the pinch-fitting sleeve comprises an elastomer selected from the group consisting of ethylene-propylene-diene rubber, fluorinated elastomer, and a combination of ethylene-propylene-diene rubber and fluorinated elastomer.
