Excerpt from Rudy, N6LF
Sometimes silver plating is suggested for conductors. The conductivity of silver is only 6% better than copper, but when the surface oxidizes, silver oxide is a much better conductor than copper oxide.

Excerpt from PolyPhaser Technical Document PTD1010
Silver oxide is the only oxide (that we know of) that is conductive. This is one reason why PolyPhaser's N-type coax connectors are all silver with gold center pins. Copper oxide is not conductive and the proper application of joint compound will prevent oxidation.

Excerpt from the freakin' ARRL Handbook
... Silver plating the tubing further reduces losses. This is especially true as the tubing ages and oxidizes. Silver oxide is a much better conductor than copper oxides, so silver-plated tank coils maintain their low-loss characteristics even after years of use.

Most switch contacts are gold or platinum plated.
Just so you know Silver Oxide in pure form is a better conductor
than silver itself is. There is none better, in fact.
"Elementally speaking, the best conductor is Silver. With respect to
compounds, however, Silver Oxide is the best conductor known to man,
short of superconducting media.
"
"Silver sulphide is a good conductor too, although not as good as silver
oxide."

"With silver, this effect is less pronounced since silver oxide is conductive. But the air gap is still there, and despite being conductive, silver oxide still has different conductive properties from those of silver the pure metal. "

Akkurat det samme står her, bare at de har byttet ut silver oxide med silver sulfide.
På den annen side:

"All of the most commonly used conductor metals (copper, silver, tin, nickel) will oxidize or corrode at room temperature in air. Please note that the primary corrosion of silver at room temperature is with sulfur, which forms silver sulfide. Silver can also be oxidized by ozone to form silver oxide, but the primary layer that forms on silver exposed to air is silver sulfide. Many cable manufacturers falsely state that the silver oxide layer that forms on their conductors is O.K. because it is conductive anyway. This is just plain wrong. Silver sulfide is actually an electrolyte, which allows the movement of silver ions and has actually been proposed for atomic switches. It is not something that you want on the conductor surface."
Uansett om dette ikke er vitenskapelige artikler så virker det som det er bred enighet om at du tar feil ang sølvoksid.
Eat your heart out!
