On a Mechanizm of an Electric Field Influence on Physicotecnical Specifications of Materials

Abstract

The paper addresses experimental data that describe a constant noncontact electric field influence on physicotechnical specifications of materials, grown in an electric field, and conditioned in it. Experiments have shown that it is possible to control physical and technical specifications of materials changing intensity of a noncontact electric field during crystallization. It is observed that an electric field influences size, optical purity and conductivity of crystals grown in a field. Crystallization of inorganic salts in an electric field allows obtaining chemically pure crystals with minimum defects. A mechanism of an electric field influence on inorganic salts crystallization is provided.

Controllable Decomposition in Ahm Crystals in Ultraviolet Radiation

“…The influence of electric field on dislocation structure of crystals is given in the paper 4 (see the list of references). Due to recently held experiments of noncontact electric field influence on the process of slow solid-phase decomposition triggered in AHM crystals by electric field [8], and results of influence of weak electric field on the process of crystallization and explosive sensitivity of these materials [9][10][11], there is an attempt in this paper to reveal an influence of noncontact electric field on a process of photochemical decomposition of wire type silver azide and lead azide crystals. The objectives of the research are the following: influence studies of noncontact constant and alternating electric field of various configuration on kinetics processes taking place in wire type silver azide and lead azide crystals after ultraviolet (UV) radiation; influence studies of low and extra-low (up to 10 -4 V/m) electric field on the process of photochemical decomposition of AHM; designing methods for controlling a reaction capability of energy-related materials.…”

The Technology of Production and Treatment of Materials in the Electric Field

“…Earlier we [4,5] established the possibility of regulating the physical and technical characteristics of materials by varying the non-contact electric field intensity during crystallization. Crystallization of inorganic salts (mono-and microcrystals of silver, lead and thallium azides; silver, sodium, potassium halogenides (chlorides, bromides)) in the weak constant non-contact electric field, as shown by our research [5][6][7], allows producing chemically pure monodisperse crystals with minimal defects. Reactivity and dimensions of the crystals can be efficiently regulated in a wide range of electric field intensity (from 10 -4 V/m to 10 2 V/m).…”

“…The method of treatment of materials in the electric field similar to the suggested one is described in works [4,5]. The unit developed in the given work provides an opportunity of inorganic salts crystallization from the saturated solutions of corresponding salts and materials treatment in the constant non-contact electric field under the certain electric field intensity.…”
