The values arise from their electronic polarization abilities, and materials with low values include perfect vacuum, gases such as helium, nitrogen, and dry air. The table below shows the dielectric constant of selected polymer conformal coatings. ...
Dielectric constant of common materials Dry air has a low dielectric constant. It can undergodielectric breakdown, a condition in which the dielectric suddenly begins to conduct electrical current. However, the breakdown is not permanent because when the excessive electric field is removed, air will ...

Dielectric Constant: The dielectric constant indicates how much a material can increase the capacitance of a capacitor compared to a vacuum. Applications of Dielectrics: Dielectric materials are widely used in devices like capacitors, transformers, antennas, sensors, and optical fibers. ...
An expression is obtained for the dielectric constant of a displacive ferroelectric in its unpolarized phase. This has been derived with the use of a Hamiltonian treated by Szigeti in connection with the temperature-dependent dielectric constant of the alkali halides. In the present work, however,...
