Randall:
I deduce from your discription that the Platimium / Palladium was deposited
on some sort of matrix and that the coating came off under differential
thermal expansion; yes?
The 98% peroxide thrusters developed--but not used--for X-37 used woven
screens in more or less the conventional manner used for silver. They
worked w/o incident in testing.

ERPS tested platinum/palladium beads in 1994. The beads work fine in an
ashtray, as ERPS demonstrated during their talks at Space Access '94 and
'95. (In '95 they scorched the tablecloth, and they were asked not to
repeat their demonstration.)
Video of a test ERPS did with a platinum/palladium bead catalyst pack
shows that the exhaust starts out white, goes clear, then turns tan.
Post-test inspection showed that many beads were crushed or absent. The
tan exhaust was interpreted as pulverized catalyst departing the engine,
and their hypothesis was that the beads lost structural integrity due to
thermal shock.

I'm pretty sure that Platinum / Palladium cat beds are proven to work
just fine and last forever running 98% Peroxide.
