“…Ceramics connect different crystal phases of two or more solid solutions of the AgBr-AgI-TlI-TlBr system. The boundaries of homogeneous and heterogeneous regions of solid solutions existence at low (298 K) temperatures were determined based on thermodynamic studies of AgBr-TlI and AgBr-TlBr 0.46 I 0.54 systems' new phase diagrams in the temperature range from 298 K to 773 K and at a pressure of 101.325 kPa [25,29,30,41] . The new systems are quasi-binary cross sections of the AgBr-AgI-TlI-TlBr section of the Ag-Tl-Br-I concentration tetrahedron [Figs.…”

The article is devoted to the technology for obtaining optical ceramics of AgBr−TlI and AgBr−TlBr 0.46 I 0.54 systems and manufacturing samples with different compositions. The new heterophase crystal ceramics are transparent without absorption windows in the spectral range from 1.0 to 60.0 μm. In the ceramics' transparency spectra based on the AgBr−TlI and AgBr−TlBr 0.46 I 0.54 systems fusibility diagrams, with an increase in the thallium halides mass fraction, as well as the replacement of the bromine ion with iodine, the maximum transparency shifts to a long infrared region.
