METHOD OF PRODUCING SILVER AZIDE MICROCRYSTALLS Russian patent published in 1997 - IPC

FIELD: synthesis of silver azide microcrystalls. SUBSTANCE: in order to obtain silver azide monodispersed microcrystalls of improved purity, solution of silver nitrate solution having concentration of 0.4 g-equiv./l is mixed with solution of potassium azide having concentration of 0.4 g-equiv./l and ammonium hydroxide having concentration of 0.02-0.06 g-equiv./l by two stream crystallization in mother liquor containing potassium nitrate having concentration of 0.1 g-equiv/l and ammonium hydroxide having concentration of 0.01-0.3 g-equiv. /l at 45-60 C at discharge rate of 3·10^-3-8·10^-3 g/equiv/min. EFFECT: more efficient preparation method. 3 cl, 1 tbl
