[time-nuts] OCXO housings - Why copper and not iron/steel?

[Mark Sims]

And (if I remember the numbers properly) Isotopically pure diamond has twice the thermal conductivity of natural diamond.  There are places that make diamond-like carbon thermal pads.  Also places that make actual diamond ones (which are not as expensive as you would think),

-----------------

> Actually, diamond has five times better thermal conductivity than silver,
so is the most conductive element, although graphene is suspected to be
better still.
