عنوان انگلیسی An Investigation of the Electrophysical Properties of Composite Ceramic Materials Containing Nickel Nanoparticles
چکیده انگلیسی مقاله The regularities of the behavior of the electrophysical properties of composite ceramic materials containing micro- and nanoparticles of nickel in the region of the percolation threshold have been studied. Regularities in the dependences of electrical conductivity, dielectric constant, thermal conductivity and thermo-emf of composite ceramic materials on the volume content of nickel particles have been revealed. When approaching the percolation threshold, the experimentally obtained dependences of the conductivity and static dielectric constant on the fractional content of nickel in these materials differ from the dependences calculated within the framework of the percolation theory in the fact that the dependence curve for the dielectric constant is similar to the curve for electrical conductivity. The origin of this discrepancy is explained by the formation of a continuous spatial structure from tunnel-connected conductors.
