I was interested in this same question with regard to UFH, under floor heating.
From what I have read elsewhere, flagstones are excellent conductors and ideal as a floor covering over UFH pipes and screed.
They conduct well, so the heat travels into the room 'easily'.
If they are thick (like the ones I'm just installing in a cottage), they add significantly to the bulk of the floor. This means it will take longer to warm up initially (and longer to cool down), so heating controls need to take this into account.
yes
semi conductor. a good semi conductor. It can also be n or p doped to increase it's conductivity
The thermal conductivity of hafnium is 23 W/m.K at room temperature.
Zinc is a fair conductor of heat, this is due to it's low melting point. And please don't assume that if it's a metal is a good conductor heat and electricity, thank you. Cristobal Carrillo
Thermal conduction is caused by two different things: Phonon conduction and Electron conduction. Electrons are thermal conductors because electrons have mass and velocity, ie. they have momentum. Thermal energy can be carried by these electrons. What makes a good thermal conductor through the energy carrying of electrons is good electrical conductor. This is because if the electrons are bouncing all around the inside of the conductor, they are transfering their energy to the molecules/atoms of the conductor and not to the other "side". More technically, the crystal lattice of the conductor must be free of as many defects as possible, and the lattice atoms must have electrons in the the conduction band. The other thermal conductor is phonons. Phonons are basically a name we give to the movement of the lattice itself. Think of phonons as waves in a pool. The better the phonon conductivity, the better the thermal conduction. Think of phonons as a rope that is held at noth ends and you whip a wave across it. If there is a lot of tention, the wave will quickly travel to the other side. If it is loose, the wave will travel slowly and maybe not even make it to the other side. The technical equivalent is high bond strengths in the lattice. High bond strength between the atoms means that the phonons will travel faster because the movement of one atom will greatly affect the movement of the neighboring atoms. This is why diamond is such a good thermal conductor, it has very very strong bonds.
Yes, that is what "good thermal conductor" means.
Graphene is the best thermal conductor. Any metal or metallic objects such as a frying pan would be a good thermal conductor, including diamond.
steel
A material that is a good thermal conductor would hold in a lot of heat. These thermal conductors would also transfer heat easily.
fabric
i forget
No.
Silver is a good thermal conductor as it's a metallic element with many free electrons available for heat transfer.
Yes, being a metal, aluminum is a good thermal conductor.
Copper is a good electrical and thermal conductor.
a metal
Conductor. You're trying to move heat, not block it.
