On Polarization in Liquid Dielectrics

The Journal of Chemical Physics, 1953
A theory of polarization originally developed for crystals is extended in such a way as to be applicable to dc measurements in liquid dielectrics. In Sec. II the general time dependent solution of the relevant differential equation is obtained by the method of eigenvalues. It leads to expressions for the ``charging current'' in Eq.

Nonlinear dielectric response of polar liquids

The Journal of Chemical Physics, 2015
The dielectric constant of a polar liquid in a strong electric field changes, in the lowest order, proportionally to the squared field magnitude. The proportionality coefficient (dielectric slope) is traditionally analyzed by mean-field models in terms of the saturation of alignment of individual dipoles as prescribed by the Langevin function.

Polarization in dielectric liquids

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1985, 1985
Measurements to verify the validity of drift dominated conduction theory, using stainless-steel, parallel-plate electrodes and purified nitrobenzene as a dielectric material show increased terminal current levels well above the theoritical levels as frequency is decreased, figure(1).

Polar Dielectrics and Their Applications

Physics Bulletin, 1980
Jack C Burfoot and George W Taylor 1979 London: Macmillan viii + 465 pp price £20 The authors have concentrated on ferroelectrics, polar materials which undergo a spontaneous polarisation capable of modification by an electric field. The first and rather larger part of the book is a basic treatment of the electrical, optical, mechanical and thermal ...

Dielectric Polarization and Electric Displacement in Polar-Molecule Reactions

The Journal of Physical Chemistry A, 2015
The aim of this work is to investigate the dielectric polarization in polar-molecule reactions in the liquid phase theoretically. On the basis of the modified Smoluchowski equation, the analytic expression of the polarization is derived. The result shows that the expression of the polarization in polar-molecule reactions is quite different from the one

Application of dielectric interlayer polarization in dielectric testing

Proceedings of 2001 International Symposium on Electrical Insulating Materials (ISEIM 2001). 2001 Asian Conference on Electrical Insulating Diagnosis (ACEID 2001). 33rd Symposium on Electrical and Electronic Insulating Materials and Applications in System, 2002
This paper researches the influence of an interlayer polarization about the dielectric characteristics of the multi-layer dielectric bodies. By using a physical model to simulate interlayer polarization found testing the tg /spl delta/-f of a multi-layer dielectric body could hardly detect the dielectric deficiency of some layer.

Dielectric Polarization and Relaxation

1984
A review of field quantities and formal results is followed by discussion of equilibrium theories and simulations for polar liquids. Relaxation processes are considered primarily in terms of correlation function treatments, starting with models of behavior in simple systems and going on to cooperative behavior in more complex systems as a function of ...

Inertial dielectric polarization

Russian Physics Journal, 2013
It is found that the accelerated motion of a linear dielectric leads to its polarization. During the accelerated translational motion of a dielectric plate, the first surface in the acceleration direction becomes positively charged. For registration of polarization charges, the metal coatings were superimposed on the plate surfaces.

On the Theory of Dielectric Polarization

The Journal of Chemical Physics, 1936
The polarization of a nonpolar dielectric in a homogeneous field is investigated from a molecular point of view. A statistical calculation of the average local field in a molecule shows that fluctuations in the induced molecular moment give rise to a deviation from the Lorentz field.

Dielectric dispersion in viscous polar liquids

1956 Conference on Electrical Insulation, 1956
The dielectric dispersion has been studied over the range 50 cycles to 100 kilocycles for the following liquids: tolyl xylyl sulfone, pentachlorobiphenyl, hexachlorobiphenyl, and solutions of tolyl xylyl sulfone in supercooled o-terphenyl. The results in all three cases conformed to the unsymmetrical dispersion equation of Davidson and Cole. A possible
