Right - the mercury pressure equalizes at the vapor pressure of the coolest part of the envelope, as long as you have enough. > Ron Soyland discovered one z566m (or zm1040?) with > intact mercury capsule - they were not able to crack it during > manufacturing.

You could calculate it if you knew your total volume, the amount adsorbed on the electrodes, and the cool spot temperature range. > anyway, thanks for info that mercury doesnt affect breakdown voltage.. Yeah, that's why mercury vapor lamps have a "carrier" gas to establish the arc. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
