Abstract
The invention concerns a silicon powder for making alkyl- or aryl-halogenosilanes, with particle-size distribution less than 350 μm, and containing less than 3% and preferably less than 2% of particles having a size less than 5 μm. Said powder enables to improve efficiency of synthesis reaction.
Claims6
Silicon or silicon alloy powder for preparing alkyl- or aryl-halogenosilanes of a particle size of less than 350 μm, characterised by a fraction of particles having a size less than 5 μm of less than 3% by weight.
