초록

A process for the production of an exothermically reacting composition, such as a propellant or explosive, containing at least one normally solid reactive constituent comprises the steps of:forming a uniform dispersion of the ingredients of the said composition in a carrier liquid;forming droplets of said dispersion;feeding said droplets into a cooling medium at a temperature below the freezing point of said carrier liquid to form solidified droplets; andfreeze-drying said solidifed droplets.

청구항

1. A process for the production of particles comprising an exothermically reacting composition containing at least one normally solid reactive constituent comprising:forming a uniform dispersion of ingredients of said composition in a carrier liquid; forming droplets of said dispersion; spraying said droplets into a gaseous medium at a temperature below the freezing point of said carrier liquid to form solidified droplets in said gaseous medium; and freeze-drying said solidified droplets.
