Have diamonds found their way into other industrial cooling solutions? With the research into gem grade diamonds, I have been expecting cheap ugly synthetic diamonds to be used in more products. I have long joked that I want a diamond frying pan.
- rbanffy 1y ago> I have long joked that I want a diamond frying pan As long as you don’t use it on a gas stove, you should be fine.
- kees99 1y agoWhy? Diamond has very low thermal expansion, so no risk of stress/embrittlement/cracks from uneven heating. Or you mean it'll catch fire? Also not a concern. That is supposed to happen at a temperature well above anything useful for cooking.
- LtdJorge 1y agoI think because it will burn your hand?
- rbanffy 1y agoThe temperature of the blue flame on a stove should be above 1000 Celsius, well above what’s required to oxidise diamonds. They won’t catch fire, but your diamond pan will erode. Once you remove it from the flame, it won’t continue “burning”. Should be safe on electrical stoves though.
- kees99 1y agoWould that >1000°C reach the surface though? There are some heady boundary-layer effects and temperature/temp-conductivity gradient physics involved here. For simplicity sake, consider a plastic [1] bag full to the brim with water, held over open flame. Will bag melt (oxidize, erode)? [1] polyethylene melts around 120-ish °C and ignites around 220-350 °C (sources vary)

- mjevans 1y agoIt's probably fine on the inside?
- IAmBroom 1y agoWhy are you using a question mark.
- mjevans 1y agoThe material would be 'fine', but I'm not sure how safe or effective it would be as I'm not a materials expert. Just considering the risk of the material. (Yeah, the material would be fine, is it safe and beneficial? That part of 'fine' I can't define.)
- rbanffy 1y agoThat's a good point. Have you done the experiment?

- Atomic_Torrfisk 1y ago> ugly synthetic diamonds Not any more, their quality has increased recently. Not that I care, wife and I did without them during our engagement.
- jrk 1y agoI think the point was not that gem-grade synthetic diamonds are ugly, but that, as industry masters gem-grade production, presumably below-gem-grade production (“ugly synthetic diamonds”) would become cheap enough to deploy in more engineering settings where diamond’s other unique properties were the key concern.

- Tuna-Fish 1y agoLarge single crystal diamond, what is required for a nice transparent screen, is still quite expensive. This article is about polycrystalline diamond, which is not really that transparent, but is nearly as good at thermal conduction as monocrystalline diamond.
- akshatjiwan 1y agoYour comment reminds me of apple's attempt to make sapphire screens. That didn't turn out so well. https://www.theguardian.com/technology/2014/feb/10/sapphire-crystal-screens-why-apple-is-interested-in-a-gemstone https://www.theguardian.com/technology/2014/feb/10/sapphire-...
- addaon 1y agoApple still uses sapphire screens on the nicer watches.
- KiwiJohnno 1y agoI have a Garmin with a sapphire screen. I've worn it every day for over 5 years, working on cars, in the garden, snorkelling on coral reefs. In short, I my watch has NOT had an easy life. I've made no attempt to protect it or taken it off for anything except charging. There is barely a mark on the screen. A sapphire screen will be a hard requirement for my next watch.
- cassianoleal 1y agoI wear mine while rock climbing. The watch has been put through a lot of beating against all kinds of rock. I've already chewed through 3 straps on this watch. The titanium case is lightly scratched, but the screen is absolutely pristine! This is my second sapphire Garmin, and it's absolutely worth the premium.
- gpm 1y ago3D printer nozzles, which is sort of the opposite (industrial heating products). Part of the argument is that better heat conduction means that you can run the nozzle cooler resulting in less heat conduction to the cold side (above where you want the filament to melt) so I guess its "cooling" in a sense too.
