Liquid sodium is more commonly used today for 100-800°C systems.

Found this on another forum,

1. Your pump is going to have to work very hard to push mercury around. The harder it has to work, the warmer it gets. The warmer the pump runs, the faster it burns out. Also, extra heat in your loop is something you generally just want to avoid, obviously.

2. Since mercury actually has a SMALLER specific heat capacity than water, it will take LESS heat energy to increase the temperature of mercury. It will conduct heat away from your components faster than water, but it will also get hot much faster than water.

3. Everyone that's seen a thermometer is familiar with mercury's behavior of expanding when heated. If you neglected to account for this in a cooling loop, you'd get a leak within minutes of turning on your system.

4. In the event of a leak, get out your wallet and buy new hardware. Mercury conducts electricity quite well, and because of it's density, it moves quite easily across even the very slightest of gradients. A drop spilled on a circuit board is almost guaranteed to short something out before it stops moving.

5. Containment.. I don't know that actual procedures used to clean up a mercury spill, but I'm quite certain you could make a plastic tray or such-like to put your tower in that would contain all the mercury if there was a leak. Wont do much if any vapors escape though, and since you'd basically be continuously passing the mercury across a heat source, vapors would be a very real concern.

That should probably be enough to talk anyone out of actually trying it, heh. And if it isn't, it's pretty expensive stuff. $71.50 gets you HALF a cubic inch. Compare that to the volume of your cooling loop (to save you some math, that's enough to fill 2.5 inches of 1/2" ID tubing).

#2 does not matter that much assuming you have an adequate radiator.

Corrected.

#2 does not matter that much assuming the loop can adequately exhaust the thermal energy which means both an adequate radiator and flow rate.

I wonder what mercury tastes like....

Agreed, you would definitely need both an adequate radiator and flow rate.

Actually none of them do at $70 a cubic inch enough to fill 2.5 inches of 1/2" ID tubing not to metion you would need a 25hp custom pump to push it 6 inches due to the masive head pressure and you couldn't use regular tubing due to the weight I don't know what mercury does to copper but do know it's corsive to aluminum

To save money on a pump you could use a 55gal drum of mercury overhead and let it slowly pass through then when it's empty use a milk jug and refill it, $70x13313 cubic inches nevermind, LOL

I could come up with 50 better ways to cool my system before using mercury
