Abstract
Temperature dependences of electrical conductivity, heat capacity and heat diffusivity in the range of 30–250 °C were studied for single crystals and optical ceramics based on metal halides of the TlBr0.46I0.54 – AgI, TlCl0.74Br0.26 – AgI, TlBr0.46I0.54 – AgCl0.25Br0.75, TlCl0.74Br0.26 – AgCl0.25Br0.75 systems. The properties of superionic conductors were discovered in materials with ionic bonds Ag – I, Tl – I with the strongest characteristics in the TlBr0.46I0.54 – AgCl0.25Br0.75 system's compounds. The influence of dissimilar ions number and their proportion in the crystal lattice was revealed by calculating the diffusion coefficients of silver and analyzing the conductivity curves. Heat capacity and thermal conductivity coefficients showed the least susceptibility to the temperature influence in solid solutions with a large number of dissimilar elements TlBr0.46I0.54 – AgCl0.25Br0.75, TlCl0.74Br0.26 – AgCl0.25Br0.75. The obtained dependencies determine the areas of materials application and allow predicting the technological modes of their processing.
期刊介绍:
Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials.
Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
