SUMMARY

The discussion centers on conducting deformation experiments on rock materials at 1000 degrees Fahrenheit and under a confining pressure of 300 MPa. Participants express concerns about the dangers associated with such high pressures and temperatures in laboratory settings. The typical method for these tests involves crushing small samples (microgram to milligram scale) between diamond anvils, with options for heating the sample chamber or using flash x-ray techniques. An alternative method mentioned includes using an ultra-high pressure air gun to fire a pellet into the sample.

PREREQUISITES
  • Understanding of rock material deformation mechanics
  • Familiarity with high-pressure laboratory equipment
  • Knowledge of diamond anvil cell technology
  • Experience with high-temperature experimental setups
NEXT STEPS

Deformation experiments (say,compression etc) for rock materials at temperature of 1000 degress and under confining pressure of 300MPa in order to explore the material behaviour.

Is such kind of test dangerous in the lab?

300MPa?! Holy crud. The 1000°F is doable (heck, you'd probably be there at those pressures). Yeah. That's a bit on the dangerous side. What kind of scale are you thinking about in terms of the test samples? I would have to do some research to see how you would even measure the deformations under those conditions. I have honestly not seen anything in my experience that could replicate that in a lab. That definitely does not mean that it doesn't exist.
 
Not really, there is a lot of pressure but not a lot of stuff.
Usual way is to crush a very small (ug-mg) sample between two diamonds acting as anvils. You can either heat the whole sample chamber of flash x-ray heat the sample as you deform it.
The alternate fun way is to fire a pellet from an ultra-high pressure air gun into a sample.
