I used to work for the Lighting division of Sylvania and we got moly wire
and parts for HID lamps from Sylvania Precision Materials in Towanda,
Pennsylvania. Lighting was sold to Osram several years ago and I don't know
if they bought Towanda too. I feel sure they would have the oxide in
Towanda.
If you take apart a junk sodium or HID lamp the wire framework inside is
mostly nickel or moly wire. If you calcine it to about cone 7 I am pretty
sure it will oxidize in an electric kiln. There is some niobium wire in the
ends of the sodium arc tubes. Don't calcine that as it will sublime as it
oxidizes and poison your kiln walls and furniture so that glazes will be
wrinkly and awful. I know I tried it once!

One other caution. Don't take florescent lamps apart since they contain
Mercury.
