Experimental Study on Charging Conditions of a Single Component DDT Detonator Using Nickel Hydrazine Nitrate
Abstract: As a salt of a coordination compound of nickel, nickel hydrazine nitrate (NHN) is an energetic substance with characteristics halfway between those of primary and secondary explosives. It is less sensitive to friction and mechanical impact than other primary explosives, although it is highly sensitive to flames. NHN is not very dangerous to handle, but it explodes readily when exposed to flame. This property makes it possible to fabricate safety …
