Ahhh.. ok. However, they were tested as catalysts - and in that
category they proved themselves inferior. I was citing the testing -
TiO2 is also a good phlegmatizer in that case.
Interestingly, over the weekend, I tested letharge as a catalyst. I
had wanted to test it much earlier but I had a hard time finding the
stuff. With just 1% added, the whistle would cycle like a strobe -
usually blowing itself out quite quickly. I think it qualifies as the
most dramatic of the 'catalysts that aren't'. I couldn't get a test
motor to complete its burn on the test stand - so I put a motor on a
stick and launched it. It popped to about 30 feet and stopped in mid-
air. It was like slow motion. The motor, when recovered, was still
well-formed in the nozzle. It makes me wonder if there might be
another use for this stuff.
Whoo 'dat plegmatizer guy? ;-}
