Catocene is nice in theory but a very bad player. TNO had an accident with it a
few years ago and they weren’t the first ones. It pretty much been banned by
the DoD. Same goes with ferrocene.

A good resource is Alain Davenas book “Solid Rocket Propulsion Technology”.
SNPE required reading.

I’m noting that if one could get around 9-10” / sec. an end-burning

grain might makes sense with rather significant effects on propellant

fraction for sounding rockets....

We played with Catocene as a burning rate modifier once. It dramatically
increases the burning rate. Unfortunately it also increases sensitivity... so
better stay below 2%. There are other organic iron compounds with better
properties though (Catocene tends to migrate to the surface over time which
significantly changes the local burning rate, which can lead to an explosion) .
As an US you shouldn't have a problem to find a supplier. For all others,
Alibaba is your friend :-)
