METHOD OF CONTROLLING OPTICAL DETONATOR TRIGGERING THRESHOLD Russian patent published in 2015 - IPC C06C7/00 C06B49/00 C01B21/08 F42C13/02 

FIELD: chemistry.

SUBSTANCE: present disclosure comprises exposing silver azide to dosed optical radiation through pretreatment of silver azide with optical radiation with wavelength of 380±10 nm and intensity in the range of 1*10¹⁴ quanta/cm² to 2*10¹⁶ quanta/cm² for 5-20 min. The detonator is then triggered with optical radiation energy higher than the pretreatment radiation energy.

EFFECT: invention provides more controllable use of detonators, improves stability of silver azide crystals with respect to thermal, radiation and photodecomposition and enables to maintain operational characteristics for storage periods of up to a year or longer without special measures.
