Propellants deflagrate. Warheads detonate. Propellant detonations are called
fatal accidents.

But 700 psi or 43 bars to have NH4ClO4 auto-decompose like a monoprop?
Can't speak for Anthony, but he said it would act as a monoprop, ie
flame would spread, at 700 psi - not that it would auto-decompose.

Matter of definition. The best way I can describe what a monoprop is, is
that it works because it relatively slowly auto-decomposes or catalytically
decomposes into gaseous products which next offer propulsion. H2O2 and N2H4
come to mind.
Detonating materials are considered propellants for guns maybe, not
monopropellants.
