Good thermal conductivity

Web30. Diamond is one of the best thermal conductors known, in fact diamond is a better thermal conductor than many metals (thermal conductivity (W/m-K): aluminum=237, copper=401, diamond=895). The carbon atoms in diamond are s p X 3 hybridized and every carbon is bonded to 4 other carbon atoms located at the vertices of a tetrahedron. Web2 Answers Sorted by: 7 Glass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered crystal structure. Since it's an insulator, the electronic contribution to the thermal conductivity is very small.
