This just tells me that diamonds are even more worthless.

[–] [email protected] 15 points 5 months ago

They always were -- outside of engineering of course.

Folks like de beers hoard diamonds and jack up prices to make folks think they are more rare that what they really are. We gotta stop the cycle and buy lab grown or use an entirely different stone all together. Diamonds are for basic bitches anyhow

One problem is that the diamonds grown with this technique are tiny

So the next we need is a way to shrink the women so that they fit.

Either JPL or LM (I can't remember which) was working on a HTHP system with the goal of being able to grow diamonds with ICs built in. I wonder if this has that potential.

Defense contractors want to grow diamond computer processors. Because silicon breaks down at high temperatures.

[–] [email protected] 1 points 5 months ago (2 children)

Don't diamonds burn? They are just carbon.

[–] [email protected] 7 points 5 months ago (6 children)

At around 1700f, yeah. Silicone burns at around half that, so it would be an improvement regardless.

Yeah, but at about 400 degrees higher than silicon.

they are small, but the large diamonds are made from seeds, so still can be used for that, or techniques can improve for larger size production in the future, also, small diamonds are useful for cutting machines

So you're saying I could get a diamond tip nozzle for my desktop 3d printer?

[–] [email protected] 6 points 5 months ago (3 children)

You can already, and for quite some time. They claim to be superior to all others.

However, the new method has its own challenges. One problem is that the diamonds grown with this technique are tiny; the largest ones are hundreds of thousands of times smaller than the ones grown with HPHT. That makes them too small to be used as jewels.

Not going to be wearing these any time soon

[–] [email protected] 7 points 5 months ago (1 children)

Not useful for jewelry, but possibly quite useful for many manufacturing or industrial purposes?

Just wear hundreds of thousands of them glued together, problem solved.

On a more realistic note though, the applications of this will probably be industrial for a good while. I found it interesting how the article mentions that they were able to develop a diamond coating over their growth substrate. That probably has some cool applications in industrial settings where diamond-plated materials are used.

Diamond saw blades are about to get cheaper

[–] [email protected] 4 points 5 months ago (1 children)

Not in a profit driven economy...

[–] [email protected] 10 points 5 months ago (1 children)

It depends; if a company can use this to make them stupid cheap, then selling them stupid cheap to undercut all their competitors could still make them more money than keeping the price the same and pocketing the saved production costs.

[–] [email protected] 8 points 5 months ago

I was making a jab. I'm aware of market forces, but price memory is a thing and often the true cost of production isn't reflected in consumer pricing. Especially when an industry just decides they can keep prices where they are if not raise them, looking at you egg producers.

These diamonds are too tiny for jewelry but I don't care.

I want a diamond heat spreader for my CPU!

Everywhere I'm looking says sold out unfortunately. I've been using Arctic Silver for over a decade with no issue though, but I'm curious.

The article shows the diamonds are around 200nm in size.

[–] [email protected] 24 points 5 months ago* (last edited 5 months ago)

Trying to size that: That's 0.2 micrometers. Fine sand is 75 micrometers to 425 micrometers.

(1000 micrometers = 1 millimeter)
