TANTALUM MEA CULPA
Following up on the recent exchange about the metal
tantalum, Alan Luedeking writes: "My apologies -- Mr.
Schmidt is right of course; moreover, I was wrong about
the conductivity of tantalum altogether: While it is quite
conductive, it is less conductive than both silver and gold,
having a thermal conductivity of 57.5 J/m-sec-deg and
an electrical conductivity of 80.321 1/mohm-cm.
Silver and gold both have significantly higher values. For
more information on all aspects of elements I recommend
the following interesting website:
I apologize to all for my misinformation!"
