METHOD OF PREPARING SILVER AZIDE MICROCRYSTALS Russian patent published in 1999 - IPC

FIELD: synthesis of silver azide microcrystals, more particularly component of initiating explosive. SUBSTANCE: in order to prepare silver azide microcrystals of monowedge modification, (β-phases of silver azide) equal volumes of silver nitrate and potassium azide solutions are mixed by two-stream crystallization in mother liquor containing potassium nitrate and potassium azide solutions and from 1,5•10^-4 g-equiv/l to 3•10^-3 g-equiv/l low-molecular nonionic surfactant. EFFECT: desired product having longer surface period and improved working characteristics (resistance to external effects such as heat, light, and radiation). 2 cl, 1 tbl
