Say you want a nonconductive high melting point, high specific heat, high thermal conductivity material, and aren't particularly worried about cost. LiH has a high specific heat and decent heat capacity. BeO has a better thermal conductivity by a factor of 20 ish, but worse specific heat by a factor of 3.5 ish. Is there a way to combine them to get some of both? Are they even stable together at high temperature?
BeO / LiH ?

Bear in mind that BeO is incredibly toxic, especially by the inhalation route.
charcoal pocofoam?
Seems nifty. Usually porous things have bad thermal conductivity. It would react with LiH, but maybe something else would work.
Also unfortunately, voltages too high for graphite are involved.
Vulcanise?
