old russian capacitors

i am from poland
the green one and two red ones are famous for palladium and platinum
but the others?

they looks like that

next ones:
vintage russian diodes
the strange capacitor
and capacitor K 52 made with platinum

and sorry for my camera!
i know bad quality
tomorrow i will make some photos

ok
what kind of metal is this?
it.s non magnetis, very breakable. from old russian capacitors.

Can't make out the part number on the outside. But you may or may not be able to use that to find whether an individual capacitor is tantalum, niobium or aluminum

i have russian capacitors which are made with palladium ( green old KM capacitor) many red ones ( which have 10% silver) but i don't know what is in these brown ones.

This one are made with palladium:




These ones are made with paladdium, as well:

Old russian capacitors KM H90 contains 46,5 g palladium and 2,5 g platinum per 1 kilogram.
Old russian capacitors KM H30 contains 50 g platinum per 1 kilogram.

This is a photo of these capacitors:

Oh nooooooo. How much of these have i chucked out?

I know the 'paint drop tantis are worth $

But the flat green ones?????

the flat gren ones have contains 46,5 g palladium and 2,5 g platinum per 1 kilogram.

in the Usa you use ounces and pounds, dont you?
so its like 0,8 ounce of palladium per a pound

I have been saving up the 'Paint drop' Tantalum capactors, and the yellow 'Brick shaped' Tantis, but in the photos above theres the same colour yellow 'Pillow shaped' capactors that i have not saved any of.

The "metal" from these old russian brown capacitors turns to white when it's on air ( it coats with a white coating ) what could it be? silver-mica?
