发明名称 PROCESS FOR THE PRODUCTION OF A PYROTECHNIC OR EXPLOSIVE DEVICE
摘要 The invention provides an improved process for the production of a pyrotechnic or explosive device containing encased hazardous solid material wherein the material is dispersed in an inert liquid, the dispersion is formed into droplets and the droplets are solidified in a cooling medium. The solidified droplets are loaded into a casing and freeze-dried in situ in the casing to produce dry particles of the hazardous material, which may optionally be pressed within the casing, advantageously under vacuum. Only the operations (if any) subsequent to the freezedrying need special precautions to be taken to prevent damage to personnel or equipment. The invention is advantageous for the preparation of detonators, igniters and other devices containing hazardous materials for example lead azide, lead styphnate, pentaerythritol tetranitrate and boron/potassium nitrate mixtures.
