Could’ve been. Manganese Dioxide is a known catalyst for HTP IIRC. With a
reactive metal in the fuel like Al, it wouldn’t surprise be for the exothermic
decomposition to provide enough energy to activate a reaction with the reactive
metal.

There is a solid compound we used to get our 98%/HTPB/AL hybrid motors ignited
spontaneously, we called it 'hypergolic paint'
. Eric Wernermont has the formula. It was gray in color, possibly manganese
dioxide.

Matthew, you might be getting confused with Nitric Acid (RFNA or WFNA). I can’t
recall any straight alcohol being hypergolic with HTP. I would definitely be
quite excited to learn if there was something not too exotic available.

Troy - believe furfuryl alcohol is one?

Why not hydrogen peroxide in monoprop or one of the various alcohols that it’s
hypergolic with?
