Capillary action with elemental Selenium

Click For Summary
SUMMARY

The discussion focuses on the challenges of converting elemental selenium gas into liquid form using capillary action at 500K and 120 PSI. The user seeks guidance on suitable materials and the appropriate inside diameter for capillary tubes. A recommendation is made to refer to an older paper that discusses the use of a Ubbeholde type viscometer, which provides insights into capillary diameter and material selection.

PREREQUISITES
  • Understanding of capillary action principles
  • Familiarity with elemental selenium properties
  • Knowledge of viscometry and Ubbeholde viscometer usage
  • Experience with high-temperature and high-pressure systems
NEXT STEPS
  • Research the properties of elemental selenium gas and its liquid form
  • Study the design and application of Ubbeholde viscometers
  • Investigate materials suitable for high-temperature and high-pressure capillary tubes
  • Explore pump systems compatible with capillary action for gas-to-liquid conversion
USEFUL FOR

Chemical engineers, materials scientists, and researchers involved in phase transition experiments and capillary action studies.

Greetings PFers.

I'm designing an experiment that needs to take elemental selenium gas at 500K at 120 PSI to a liquid form at any temp and pressure. I would like to use capillary tubes in conjunction with a pump to convert the gas to a liquid.

However, I'm having difficulty finding information on capillary action when using elemental selenium. Primarily, what material do I need to use and what inside diameter. Can anyone point me in the right direction or give me a tip?

Thanks!

check this paper out. its old but they used a Ubbeholde type viscometer. they describe capillary diameter and material.
