Аннотация: Based on analysis of the electronic configuration of the impurity in minerals have a crystalline structure such as NiAs (eg, pyrrhotite), a correlation of electrical conductivity, density impurity atoms, and the density cation vacancies. The density cation vacancies increases with the total density of the impurity atoms increases, Показать полностьюthus reducing the conductivity of the crystal decrease. Shown that the nature of these phenomena - decrease in the concentration of electrons in the conduction zone as a result of the capture of an electron vacancy impurity atoms. On the basis of calculations of the density impurity investigated the properties of anionic impurity atoms and analyzed the mechanism of isomorphic substitution of sulfur ions in the structure of pyrrhotite.
