New Glasses in the PbCl2–PbO–B2O3 System: Structure and Optical Properties

New oxychloride lead borate glasses in the xPbCl2–(50-0.5x)PbO–(50-0.5x)B2O3 system were synthesized with a maximum chloride content of 40 mol%. The characteristic temperatures and mechanical optical properties studied. incorporation led to significant expansion transparency range UV (up 355 nm) IR regions 4710 nm). Decreases Vickers hardness, density, glass transition temperature consequences change structure. studied are promising materials for photonics optics. structure PbCl2–PbO–B2O3 was analyzed detail using vibrational spectroscopy X-ray diffraction.
