Density dependence of dielectric permittivity of water and estimation of the electric field for the breakdown inception

Abstract

Density dependence of the dielectric permittivity for water was obtained using the molecular dynamics method for the supercritical region at T = 670 K in a broad range of density, and for T = 300 K and T = 350 K near the coexistence curve. Critical values of the electric field strength which make possible the spinodal decay "liquid-vapor" were calculated.
