Re: [neonixie-l] How exactly does mercury increase Nixie lifetime?

Hi, the mercury adheres to cathode surface and because its molecule is heavy, it is less likely to be relieved from the cathode by electrons bombarding the cathode (compared to relatively light molecules of Fe, Ni, Cr - stainless steel).. The lifetime of mercury doped nixies is 200.000 hrs, tubes

Hi All, Just wishing to introduce myself to the group, and hope to learn what I can. I currently ( blatent plug ) make and sell Nixie clocks on eBay and online www.bad-dog-designs.co.uk Best wishes, Paul -- You received this message because you are subscribed to the Google Groups

Hi Paul, Welcome! Very nice clocks - I like the sawn-down chassis that will wall mount - neat. There's a good smattering of nixie types in the UK - fairly evenly distributed from the Far North to the Far Warmer South! Cheers Nick -- You received this message because you are subscribed to

Hi Nick, Thankyou for the Welcome, and for your kind comments! Not that warm in the South at the moment :) Cheers, Paul -- You received this message because you are subscribed to the Google Groups neonixie-l group. To unsubscribe from this group and stop receiving emails from it,

Re: [neonixie-l] Cathode Construction: material? thickness?

Nothing else than stainless steel makes sense. Just as You wrote, 304 SS is very easy to get and with a mercury makes unbeatable combination. Molybdenum (and possibly tungsten) is more resistant to sputtering (without mercury), but I dont know any nixie tube using a moly cathodes.. Only SS.

Re: [neonixie-l] Cathode Construction: material? thickness?

Moly without mercury is more sputter resistant than SS without mercury ;-) I havent seen any study about those metals with mercury.. Take a look at the Weston's book, there is a whole chapter about sputtering. Just skip the formulas with strange mathematical symbols and You will be on neat graphs

Re: [neonixie-l] How exactly does mercury increase Nixie lifetime?

Do you know of any papers or studies detailing this discovery? Patents even? Surely someone had to have discovered this, but it is just taken as fact in the few references I find. Not that I'm doubting that mercury does indeed extend tube life, but I have to wonder who first happened upon this.
