Ptaskmaster, watch for the NR of flag early next week.Flag will not only be a major Canadian player in palladium, it is also in the supreme position for rare earth minerals AND gold.So to speak hit 2 flies with one swat. Also an assay is being done on a hole drilled not to long ago at Sylvan Lake, which has strong showings of chromium and cobalt besides palladium , platinum,nickel,copper, gold and silver! what else does one want?? just excuse my blah, blah, I am getting excited.

Hi Ptask, I have checked and, yes, platinum, palladium and rhodium do perform different functions in an automotive exhaust catalyst. Rhodium is used because it deals with nitrogen oxides (NOX), whereas platinum and palladium deal with the hydrocarbons. I have found a very informative site which deals with these, and many other, PGM issues. See; europa.eu.int Regarding the matter of substitution, I would expect that experimental data is available for all sorts of catalyst mixes. But I don't think that it would be the technical side of things that would slow down substitution of, say rhodium, but rather the regulatory testing and regulatory process that will slow things down.
