In 2010 researchers at the Royal Institute of Technology (KTH) in Sweden announced the discovery of new compound, trinitramide N(NO2)3, which could revolutionize production of solid rocket propellants. Seems like the new compound is a candidate for ideal rocket oxidizer because it has several key advantages:
chlorine free, therefore green propellants could be made out of it,
high oxygen content, 63.15%, among the highest of all known oxidizers. This means efficient combustion,
high density, 20-30% greater density impulse could be achieved compared to best current formulations,
High positive enthalpy of formation because compound has 4 single bonded nitrogen atoms. This means additional energy for rocket aside one achieved from combustion.
But since the announcement of discovery, not much was published about further developments. Is there any practical application of this compound, or it remains just a lab curiosity? What prohibits its mainstream application - production difficulties, cost, stability issues, compatibility with binders, high pressure exponent or maybe something else?
