Precision Measurement of the Microwave Dielectric Constant of Liquids

Journal of Applied Physics (1965)

E. Fatuzzo P R Mason

A method utilizing reflection measurements on a liquid-filled line section terminated in a short circuit is described. Its chief feature is the use of line lengths such that the impedance at the liquid surface is real, which simplifies the calculation ofε* from the measurements. Additionally it reduces systematic errors due to the window used to constrain the liquid surface, and the nonzero impedance of the sliding plunger used to adjust the length. These factors give errors inε′ about an order of magnitude below those inε″. This makes the method particularly suitable for determination of the dielectric relaxation time of solutions of polar in nonpolar liquids. Limits on the window and plunger parameters to give an accuracy of about 5% inε″ and 0.5% inε′ are derived. Results of measurements with equipment satisfying these requirements are given, and it is seen that relaxation times can be found to about 5% accuracy for solutions 1–10 Molar % nitro-benzene in benzene.

A method of measurement of the microwave dielectric properties of weakly polar liquids

Journal of Scientific Instruments (1965)

E. Fatuzzo P R Mason

A method for measuring the complex dielectric constant of weakly polar liquids is described. The measuring cell consists of a short-circuited piece of waveguide (or coaxial line) filled with liquid up to a level such that the impedance is real at the liquid-air interface. The method is particularly suitable for the accurate determination of the relaxation time of weakly polar liquids or of dilute solutions of polar liquids in non-polar solvents.

DC and AC electrical conduction in single crystal alumina

physica status solidi (a) (1976)

H. M. Kizilyalli P R Mason

The conductivity and permittivity in the c-direction of single crystal boule sapphire slices and flux grown platelets have been measured over a temperature range of 700 to 1500°C, an oxygen partial pressure range from 1 to 2 × 10−2 at, at dc, and over a frequency range from 70 Hz to 5 MHz. A surface and a bulk process are postulated, and the electronic or ionic nature of the latter discussed. La conductivité et la permittivité dans la direction c des tranches de boule-saphire et des plaquettes formées à l'aide d'un flux – toutes deux unicrystallines – ont été mesurées selon une gamme de temperatures se rangant de 700 à 1500°C, et également sous des presions partielles d'oxygène allant de 1 à 2 × 10−2 at, avec courant continu et des frequences de 70 Hz à 5 MHz. Deux processus, l'un d'électrode et l'autre à l'interieur du cristal ont été postulés, et le caractère électronique ou ionique de ce dernier a été consideré.

A calculation of the complex dielectric constant of a polar liquid by the librating molecule method

Proceedings of the Physical Society (1967)

E. Fatuzzo P R Mason

The dielectric constant of polar liquids is calculated by assuming a model of the molecule which describes its interaction with the electric field and by introducing means of calculating certain averages demanded by the statistical mechanical theory.

A theory of dielectric relaxation in polar liquids

Proceedings of the Physical Society (1967)

E. Fatuzzo P R Mason

Two types of methods have been previously used to relate the macroscopic decay of polarization in a dielectric specimen to a microscopic decay function defined in terms of molecular motions. The first is based on Kubo's theory of non-equilibrium statistical mechanics combined with Kirkwood's theory. The second is based on the use of Debye's rotational diffusion equation.
