Abstrakt: New chloroantimonite glasses were obtained in the SbO - PbCl -AgCl ternary system. Their thermal, optical, and mechanical properties are studied. The concentration of silver chloride increases at the expense of antimony oxide accordingtothe following composition rules: (80- x)SbO -20PbCl - xAgCl and (70- x)SbO -30PbCl - xAgCl. Depending on the AgCl content, Vickers microhardness varied between 110 MPa and 140 MPa. The elastic moduli were measured by ultrasonic velocity. The optical transmission range extended from 400 nm in the visible spectrum to 7 μm in the infrared spectrum. The refractive index was close to 2. The glass transition temperature measured by the DSC ranged from 250 to 290°C. It is shown that the glass transition temperature decreases as AgCl substitutes for SbO and a more stable system was with 20% PbCl in the (80- x)SbO -20PbCl - xAgCl. [ABSTRACT FROM AUTHOR]
