Tantalum caps are electrolytic type.  The original reference speaks of 
multilayer capacitors, those are ceramic.  Wikipedia says that indeed palladium 
(and silver) were used in early generations of those devices, to be replaced by 
nickel and copper later on due to cost pressures.

So it's possible.  And today the price per ounce of Pa and Au are about the 
same.  I wonder how much metal is in ceramic capacitors...
