"New" diamond growing process

[aramis]

I was browsing in boredom, and stumbled across the following

http://video.nationalgeographic.com/video/science/weird-science-sci/idkt-diamonds/ (it's about 3 min 30sec long).

Note that about 3/4 of the way through, they start talking about a low pressure plasma method of growing diamonds... and show sheets of the stuff. several inch diameter disks of the stuff. And it's a really good thermoconductor!

So, I figured I'd point this out, since it's the first I've heard of it.

cool

Thanks for the link.

diamond or cubic zirconia has been available for years?

Back in the day I set up and installed for several compaines things like hot isostatic presses (HIP furnances) to make things like artificial diamonds and cubic zirconia.

The process is not cheap, let me tell you....

The ones I installed went to about 3000 C at about 200,000 to 500,000 psi or greater.

You rebuild all the pressurization pumps after each run.... I wonder why...?

Cubic Zirconia isn't diamond. It's Zirconium dioxide ZrO2, not molecular carbon.

Artificial diamonds by seed flake plus pressurized carbon are a different process.

Thanks for the info... the video was not playing for me.
