Dielectric Constant Chart of Gases

  • #1

Main Question or Discussion Point

Is there a creditable chart out there - on the dielectric constant of gases? What is the dielectric constant of Sulfur hexafluoride (SF6) compared to other gases or other gases in a vacuum?

Thank You

CRC Handbook good enough for you?

Why do you want to know? As concerns applications, dielectric constant of SF6 is unimportant. Important is its' dielectric strenght.

Looking for the best “Electromagnetic shielding”

Looking for the best way to contain a magnetic field.

Thank You

a magnetic field.
And dielectric constant has what to do with magnetic fields?

dielectric huh? Well then, to quote The Princess Bride, "I don't think that word means what you think it means".

A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor.

Thanks for helping me out with comparing and contrasting dielectric materials to magnetic shields.
