Abstract

Metallic silicon for the Rochow-Synthesis is reduced to particles measuring at least 5 mm in their smallest dimension and 15 mm in their largest dimension, cooling the silicon from a temperature of at least 700.degree. C. to at most 120.degree. C. within a maximum of 2 seconds, and then ground and reacted.
