Re: Use of rhodium in cars (cats and general)
From what I read there's about 1-2g of rhodium in the average cat. The exact amount can veary according to the size of the cat and the manufacturer's "recipe". It may be possible to correlate an engine's propensity for producing NOx, CO, and other bad gasses to the size of cat needed to reduce them to fed mandated levels.
Rhodium is primarily mined for use in catalytic converters and other catalyst operations. A minor amount is used in jewelry industry as a dip plating. There is no other area on a vehicle where rhodium would be used.
Fancy object huh? We love long stories here...do tell. Don't think I want to hang a cat around my neck as "bling" though, unless it's nice and polished up.
