BINARY PYROTECHNIC MIXTURE EMITTING IN THE NEAR INFRARED Russian patent published in 2017 - IPC C06B43/00 C01G3/14 

FIELD: chemistry.

SUBSTANCE: binary pyrotechnic mixture, emitting radiation in the near infrared region consists of an oxidant - zinc peroxide and a fuel - cupric salt with sulfur mercapto compounds, bound in -SH group, or cuprous salt with thiocyanate. To obtain the composition the fuel is dissolved in a suitable solvent and then deposited using a copper salt, preferably cupric chloride dihydrate, to obtain salts. Using tracer compositions based on this invention does not require any additional auxiliary pyrotechnic systems.

EFFECT: pyrotechnic mixture meets the basic requirements for special infrared tracer compositions and tracer compositions in general.
