Best solder for tantalum?

G01

Hey there,

I have to solder to tantalum for a project I'm working on. I hear this isn't easy with conventional solder. Is there a certain type of solder I should use, or should I go about a different method, silver epoxy, etc.? Thank your for the advice.

Conventional solder will not work with tantalum, which is a refractory metal. I'll check with some people I know who are involved with Ta and find out what they recommend.

To what material is one joining the Ta?

I believe one normally brazes Ta, which is usually case for refractory alloys. Also, one has to keep air (oxygen) away from the Ta, Mo and other similar metals.
