Abstract
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 m. 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.
