Discussion Overview

The discussion revolves around the potential applications and implications of newly developed larger and better diamonds, as reported by the Carnegie Institution. Participants explore various uses in engineering, science, and industry, touching on optical, thermal, and mechanical properties.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that larger diamonds could have interesting optical uses, particularly in windows or lenses for chip lithography, due to diamond's high refractive index.
  • Others mention that diamonds have the highest ratio of thermal conductivity to electrical resistance, making them ideal substrates for chips if they can be better matched to silicon.
  • One participant recalls that diamond anvils are used for high-pressure applications and speculates that larger diamonds could enable larger experiments.
  • Another participant notes that larger diamonds could mean lower pressures when used as anvils, while also questioning if the new synthetic diamonds might be stronger than natural ones, potentially allowing for more pressure to be applied.
  • It is proposed that larger diamonds on diamond-edged saws would result in coarser grit, leading to faster cutting in industrial applications.

Areas of Agreement / Disagreement

Participants express a range of ideas regarding the applications of larger diamonds, with some agreeing on potential uses in optics and industrial applications, while others debate the implications of size on pressure and strength. No consensus is reached on the overall impact or specific applications.

Contextual Notes

Some claims depend on the definitions of strength and pressure in the context of diamond anvils, and there are unresolved assumptions regarding the properties of synthetic versus natural diamonds.

The Carnegie Institution found a way to make bigger and better diamonds. What are the potential applications for this? What does this mean for engineers and scientists?

Could have interesting optical uses - especially for windows or for lenses in chip litho steppers.
Diamond has the highest refractive index - although it would be a bugger to polish.
It also has the highest ratio of thermal conductivity to electrical resistance so is an ideal chip substrate if you could get it to lattice match silicon a bit better.

Most industrial uses as abrasives use diamond dust, this is cheaper than CVD diamond anyway.

I seem to recall that diamond anvils are used for extremely high-pressure applications. Perhaps larger experiments could be conducted with the new diamonds.
 
You normally use the anvil to concentrate force at a point - larger diamonds mean lower pressures.
I like topher's suggestion - presumably larger diamonds work on larger women?

Agreed, but the article seemed to indicate that the new synthetics might be stronger than natural diamonds, due to fewer defects. Wouldn't that allow for more pressure to be applied?
 
Larger diamonds on a diamond-edged saw would equate to courser grit, so the saw would cut faster. (The same, of course, for diamond sanders and all sorts of industrial applications.)
 
Topher's post pictures it ALL!
