Abstract

This invention comprises a process for the preparation of a smoke composition based on hexachloroethane, zinc oxide, and metal powder, in which zinc oxide granules obtained by high compression and subsequent crushing are used as a mixture component and the intermittent burnoff of previous smoke compositions of this type is thus avoided; the invention also concerns a smoke generator filled with such a smoke composition.
