That should have been Pd 77% not Pd 67%.
Jones,
Thanks for the clarification regarding the JM Pd. I don't see in the
document that you are citing that "JM Pd" in table 10 is referenced
to "JM Pd Type A" that is apparently an alloy of Pd 67% and Ag 23%.
Where does it say that the "JM Pd" in table 10 is "JM Pd Type A"? Are
you saying that all "JM Pd" is an alloy of Pd/Ag? Thanks for any
information you can provide.

I should add that the precise atomic ratio of 77/23 in the alloy
known as "Type A" which was discovered in 1930, is not arbitrary and
is a critical parameter. Brian Ahern and Keith Johnson discovered
the superconductive aspect (Tc) was maximized in an alloy at this
precise ratio in a sharp peak, as is proton conductivity. If a
different ratio is used, success is problematic, since proton
conductivity comes first. For instance a 50/50 alloy would possibly
fail to load hydrogen at all.
Since Pd as a pure metal is denser than Ag by a ratio of 120/105 the
optimum alloy ratio, if stated by mass, is different than the atomic
ratio - and alloys are often designated by mass - so you can see the
problem with proper labeling.

Thanks Robert. I should have spent more time on the explanation of
that table, but the post was already getting too long.
The "JM Pd" is type A which is 23% Ag. This was apparently
successful 17 times out of 28 including the hero effort which was 7
times more P-out than any boron run.
The unsuccessful "NRL silver alloy" is a mystery and it does go
against the contention that silver is the critical component, but
they did say that deuterium loading was poor for the NRL sample,
hence excess-heat production was not likely. Why loading was poor is
not stated.
When silver vapor is used - as in Mills Sun Cell experiment, loading
becomes a non-issue and surface area is maximized.

Looking at Table 10 in the document cited, it would appear that
Boron is the smoking gun, not silver. In fact Pd-Ag never worked but
Pd-B worked 7 out of 8 times.
