Process and apparatus for preparation of finely grained lead azide |
摘要 |
The invention provides a process for the preparation of finely grained lead azide, in which aqueous solutions of lead nitrate and sodium azide are stirred in a vessel at constant temperature, characterized in that in a first process step the aqueous solution of lead nitrate and a small amount of an aqueous solution of sodium citrate are poured into the vessel, in a second process step, the aqueous solution of sodium azide is dosed into the vessel over a period of time of 30 to 40 minutes, the aqueous solutions poured into the vessel are agitated at a peripheral stirring speed of between 0.2 m/sec and 1.0 m/sec., and the constant temperature is set to a value of 50 DEG C. to 80 DEG C.
