The theoretical steady detonation velocity when the diameter is beyond the maximum value
works well as liquid explosives. Table
7.42
shows the component and properties of
one group of liquid explosives with aliphatic amine as the combustible agent [
58
].
In Table
7.42
, hydrazine nitrate serves as the oxidation agent. Actually, nitrate
for alkaline metals or alkaline earth metals should also be added to form water-
soluble composite oxidizers. Content of hydrazine nitrate is required to be over
60 %. Some aliphatic amines can be used as combustible material, such as etha-
nolamine, diethylenetriamine, methylamine, and methylamine.
