Comments by "" (@Gameboygenius) on "How a CVD Diamond is Made" video.

  1. After digging through the literature this seems to be incorrect. Isotopically pure diamond, whether C12 or C13 have a drastically increased thermal conductivity over a mix of isotopes. (Naturally occuring carbon is 1.1% C13.) However, the relationship is symmetrical and either C12 or C13 will do the trick as long as it's pure. C12 would be the obvious choice for industrial production due to lower cost.

  2. The mined stuff? Probably not. Synthetic silicon carbide does see some use in specialized high power transistors.

  3. ​ @joefekete4384  Each to their own, but if he did that I would frankly unsubscribe. As a point of reference, when Thoisoi2 (a chemistry/science youtuber) switched to using a voice talent, a lot of people were clear in the comments that they didn't like the change. In his case, it seems like it was his own decision, stating that speaking English was mentally taxing for him. Nevertheless, the public opinion was clear in that case.

  4. Diamond is an excellent heat conductor. You want the heat shield to block heat, so the exact opposite.

  5. It's not exactly the same thing but some people have experimented with making rubies in a kitchen microwave.

  6. What was the context of the question on Physics SE? Diamond production or why 2.45 GHz is used in general? If some other frequency was found to be orders of magnitude more effective for this purpose somehow, I'm sure you could solve the regulatory issue. Apply for a special license and/or build a giant faraday cage around the equipment. If there's a will (and money to be made) there's usually a way.

  7. Well, the refractive index, thermal conductivity and Mohs hardness rating are all pretty impressive. The mining is just meh. However, Fiona Apple also said in the song "and why men buy them", and it's generally not for the tech specs.

  8. ​​ @bill6255  That's not what he said. Defects in the technical sense. Lattice defects. It makes the product less brittle and less prone to cracking so it's a good thing.

  9. I don't know. I think Jon is more of a 9N purity silicon kind of guy.

  10. He already did... Sort of. Did you see the one on atomic layer deposition?
