For the high voltage generation of CS, you use very small electrodes,
not large ones. You use large ones for low voltage CS. The trick it to
get the high density of silver ions away from the electrode before they
can aggregate sufficiently. For low voltage that is done by Browning
movement and stirring, thus the very limited 1 mA per square inch. For
high voltage systems, you want a huge gradient near the electrode, so
that the ions are sucked away from the electrode by the electric field.
I am not sure what size you would want for 500 volts, but for 10,000
volts I found that the electrodes should be about .03 square inch each.
With the system I was using with 100 mA of current, that gave a density
of about 3 amps per square inch. I am not sure 450 volts is enough to
provide the necessary gradient to prevent larger particle size. The way
I kept the electrode that small was to feed some 14 gauge silver wire
into glass tubes, and only allow about 1/8 inch to protrude from the end
under the water. Then I mounted it so that the tip of the two
electrodes were about 1 inch apart. You may find that keeping it cool
is a problem because of the high power.

Thanks for the warning about the cap. I made sure I discharged that
before going into the electronics too far.
Yes, I heard that the microwave electronics produced pulsed DC.
At this stage I am looking for evidence of the system being able to
produce small enough particles before I have a large electrode
fabricated just for the purpose. Just seems I couldn't make a big
enough electrode practically to be able to make small particles but I
don't really know.
Boy sure would be good to make a fine quality CS this way since it is
so fast at a quart under 2 minutes . However safety and quality are
the main requirements for any system and product.
Thanks for the tips and any other comments on this or other systems
are welcomed.

A microwave magnetron runs on HVDC and the box has a power level

Using microwave parts is extremely dangerous. The voltages
are high, the capacitances big, and currents unlimited. There
has been some discussion of using microwave transformers, but
I thought those were for HVAC not HVDC. I see no way to
produce small particle CS using high voltage DC as the
currents would be way over the optimum of 1 mA/in^2

Hi-
I am new to the group here. I was referred to this list
by a fellow who says there was some experience here
amongst your ranks using microwave transformers and
capacitors etc to make CS using high voltage DC.
I wanted to go to the archives to have a look around but
that section is not functioning at the moment and so I
thought I'd just ask the group instead.
I have been using low dc Volt system for making a fine
quality CS for 5 years already. Because of demand from
family and friends I need to increase my production.
I found some instructions on the internet from a kind
fellow on how to connect the microwave components together
to create such a system but not much more details then
that unfortunately. I tried it and the initial results
are encouraging. I only have a TDS meter on hand and so am
not really sure about the quality of the product. Also I
only had wire type of electrodes and did not have the
wider pieces of silver and so I fear I am making too large
of particles.
Has anybody here used this type of system and if so have
they had their product analyzed for true ppm, particle
size and % of ionic/colloid content etc. ?
any information on this will be appreciated.
best regards,
PG50
