o2 sensors

[ritehere]

Has anyone sold any of these on ebay? Just seems like they would get the best price there. And I would think that you would process them like cats.

O2 sensors are evry easy to chemically process but quite a pain to prepare.
Anyway, depends on the application which it was pulled out of, you usually find pure Pt wires and a ceramic section plated with Pt.

Nice source for pure Pt, but lots of work :|
