Hydrazine nitrate is an inorganic compound with the chemical formula N₂H₄·HNO₃. It has usage in liquid explosives as an oxidizer. It exists in two crystalline forms, stable α-type and unstable β-type. The former is usually used in explosives. Its solubility is small in alcohols but large in water and hydrazine. It has strong hygroscopicity, only slightly lower than ammonium nitrate.^[1]

Hydrazine nitrate has a good thermal stability. Its weight loss rate at 100 °C is slower than that of ammonium nitrate. Its explosion point is 307 °C (50% detonation) and explosion heat is about 3.829 MJ/kg. Because it has no carbon elements, the detonation products are not solid and their average molecular weight is small.^[1]

Production

Hydrazine nitrate is produced by the reaction of hydrazine and nitric acid:^[2]

N₂H₄ + HNO₃ → N₂H₅NO₃
