so has anyone tried this, it seems good to me, if nasa can use it in the reentry shield on a space shuttle that means it can dissipate heat well, and i have access to a kiln to fire it and get it looking good, so opinions

Its not that the ceramics are good at dissipating heat, they are actually just really good insulators (meaning they dont let the heat penetrate them). That keeps the people inside the shuttle safe.

Interesting idea. Ceramic is an insulator though so would not transfer the heat very well if at all.

Ceramic heatsinks DO NOT transfer heat that is why they're on the bottom of the space shuttle.

I would tend to think that NASA uses ceramic for its insulating properties rather than high thermal conductivity, but then again, I'm not a rocket scientist. <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink"> I do know that several types of ceramics would be very unsuitable for heatsinks, but there may be some particular types that could work.

on the other hand they use ceramic in capacitors. maybe it's not the sam but who knows

NOOO. Stay away from Ceramic..It just keeps heat in and will cause more issues than its worth. Ive been there and there really poor..I cnt remember the name of it but its main material property was Ceramic mixed with something else.

Here is some info:<br><a href="http://matse1.mse.uiuc.edu/ceramics/prin.html" target="_blank">http://matse1.mse.uiuc.edu/ceramics/prin.html</a><br><br>
Thermal Conductivity (W/m K)<br>
Copper = 398<br>
Aluminium = 247<br>
Fused silica = 2.0 (Amorphous fused silica is used in the space shuttle)

</div>Off topic: Click on that link. What is the difference between Aluminum and plastics? HA! I've always said plastic cases were idiotic. Aluminum cases FTW! Ambient temps DO have an impact on the actual casing.

Ceramic no, Diamonds yes. Diamonds = expensive and nearly impossible to lap with any precision due to their brittleness. <br />

Carbon nanotube heat sinks on the other hand....<br />

EDIT: Little article about simply adding nanotubes to epoxy, amazing results. Keep in mind a gram of nanotubes is about 500$.

Hey Y'all, What about Ceraminique? They say it has ceramic in it...<a href="http://www.svc.com/chidethcobya.html" target="_blank">Céramique 2.5g High Density Thermal Compound by Arctic Silver (Free First Class Shipping)</a>

Good for underclocking if you don't want your temp to fall below 50 <img alt="" class="inlineimg" src="/images/smilies/tongue.gif" style="border:0px solid;" title="Stick out tounge caps">

I've tried that...made of metal oxides. It's not as good as AS5. Upside? A single tube is titanic. WIll last you the rest of your natural life.
