and the use of nano materials as gelling agent stimulate actual research
activities.
Neutral Burning
Burning of a propellant grain in which a reacting surface area remains
approximately constant during combustion (W Burning Rate, Progressive
Burning and Regressive Burning).

Nitroaminoguanidine is obtained by reacting W nitroguanidine with
hydrazine in aqueous solution. Nitroaminoguanidine has gained a
certain attractiveness as a reduced carbon monoxide propellant because
of its ready ignitability and its burn-up properties.
Nitrocarbonitrate
NCN; N.C.N.
Nitrocarbonitrates are relatively low-sensitive explosives, usually
based on ammonium nitrate, which do not contain any high explosives
