I used to buy for recycling catalytic converters from cars and processed some as well . Actually the amount of platinum used is rather small its only added as is
done for some lab uses as for example a small volume of platinum chloride was added
to asbestos and then heated to reduce the platinum to metallic fine particles again
with a much larger amount of asbestos than platinum so as to keep it inexpensive .
In pure powder form i often amuse my friends by blowing methyl alcohol fumes from a
small piece of tissue over the platinum and it will heat up instantly and glow red
hot very neat for hand warmers if you don't mind or can deal with the tendency to
form formaldehyde . Lately I have been thinking about making a small nitinol or
biometal motor using this property for super small fuel powered motors they have
been using batteries . Yes I think you might be able to recycle the platinum from
old ones , I know the catalyst can become poisoned and I assume this could happen
with old heaters and recycling renews it .but it might be to difficult for you . I
know I could but it might be to much typing for a process you might not want .
However you can buy platinum chloride but be prepared to pay 10 or 20 times the
market value of the platinum if from a lab supplier , its why I always save some of
my metals . But do try some of the companies that buy precious metal scrap as I
have gotten excellent buys in such metals for example tantalum for 40.00 per pound
, and dissolve the platinum in your own aqua regia , its slow but will dissolve .
Repost with any extra questions on how to do this if you need to
