Things I Won't Work With: Dioxygen Difluoride (2010)

I think there's some stuff in a book called Ignition about experiments using Fluorine as an oxidizer in rocket engines to get a little better specific impulse than oxygen. Only problem is that the exhaust is hydrofluoric acid at thousands of degrees. Yipe.

> a book called Ignition

that book is really good and has some interesting hidden treasures, like a couple of sentences about adding silicon oil to the fuel mixture to create a self-ablating film on the combustion chamber. I think some amateur bi-prop engine guys use that in their fuel setups. It's funny how the book ends after all that research and exotic chemicals with JP-1 and liquid O2 are still pretty much the best combination.
