Anti seize pastes are typically colloidal nickel in a silicone oil
carrier. Older (19th century) were colloidal copper is an organic oil
carrier.

For best thermal conductivity and resistance to degradation, use a
silicone grease. Note that silicone greases are not actually a grease,
they are thick oils. A traditional grease is solids suspended in oil.

I use silicone greases developed for laboratory use (chemical and heat
resistance) for electronics. One such is (was) Dow-Corning 510.
