Now this may sound a little strange but I am having a discussion
in another audio group and need some "hard evidence" on this
subject.

The other party has made this statement:

"Silver Oxide is an insulator - no resistance value can be
ascribed"

I believe it to be incorrect and at least Silver Oxide is a
semi-conductor or has a measurable resistance.

Despite intensive Googling I (or the other side for that matter)
can not find any reputable site that will verify/disprove this
point.

So guys I know there are some fairly cluey people out there so
how about offering an answer and some proof? Preferably
something referenced to a text book, university or research
institute. I am not interested in any "snake oil" sites.

One further point Silver Sulphate (the dark tarnish that forms)
is *not* the point in question I am only concerned with Silver
Oxide - Silver that has reacted only with oxygen.

**sci.electronics.design would be a better group, IMO. PA hasn't posted
there in many months. He was laughed out of the place. There's some pretty
smart guys there too. I've checked through my partner's University chem
books, but had no luck in finding the information. Given that there's a
whole battery technology based around silver oxide, it is reasonable to
assume that the stuff is pretty conductive. I dunno enough about the
chemistry though.

Thankyou for that. To play the Devil's Advocate could it be
argued that "The cable manufactures have a vested interest in
this and so their *opinions* are biased and so can be
discounted"?

The welding site was good but lacked depth. I was hoping for a
definitive and unquestionable site that would be beyond reproach
;-)

Thanks TT

I rather think the conductivity of a commonly occuring chemical
can be evaluated quantitatively and asserted factually.

Try to get scientific then.

You probably need to dig around for a physics handbook that has
some material on electrical conductivity. Try this:

: www.belden.de/daten/belflex_triax.pdf doesn't mention Silver

So I really need something very specific and there is huge
confusion with Silver Sulphide.

********! Atomic oxygen sensors (rocket science, note) can be made
from thin films of silver which increase in resistance as they are
oxidized. Eventually the resistance goes way up (orders of magnitude).
Been there, done that.

"As silver is converted to its non-conducting oxide the resistance
increases" http://lasp.colorado.edu/strv/exp1a_strv.html

Heck, I suppose high-end silver oxide could be different.

Hardly but at least(tm) it is soft.

"3.2.2. Silver oxide. - Silver oxide is easily broken down by contact
pressure and forms less readily at elevated temperature. Thus it is
good practice to silverplate copper contact surfaces that must be
operated at elevated temperatures." -

Heck, I just hand them in to lost property and hope the owner claims
