The paper is focused on the effect of homogenous and inhomogeneous magnetic fields on crystallization, and some physical and chemical properties of silver azide (morphology, electric resistance, defect structure, reactivity) as well. The authors put forward an efficient procedure for growing crystals with specified sizes, reactivity and minimized impurities.

The experimental results show that the relative permittivity in the threadlike silver azide crystals changes under the influence of the polarization field (10-3 ÷ 103 V/m). An amount of the formed intermediate product at a weak noncontact electric field decreases significantly that allows assuming that polarization influences primarily, at the stage of formation of the silver azide decomposition intermediate. The polarization in a constant noncontact electric field may be regarded as a control method of explosive sensitivity.

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.
