摘要

40B2O3-20SiO2-20P2O5-(20-x) Li2O-xTiO2 glasses containing B2O3,SiO2,P2O5,Li2O and variable amounts of TiO2 were formed using the melt-quenching procedure. The absence of Bragg’s peaks suggested that every sample was amorphous in XRD spectra. The increase in density, ultrasonic velocity, and elastic moduli of the glass samples as the TiO2 level increases suggests the formation of a more expanded structure with greater TiO2 content. Both the ultrasonic velocity ( \({V}_{L}\) V L ) and shear ( \({V}_{S}\) V S ) have increased. ( \({V}_{L}\) V L ) increased from 5070 to 5495 m/s, whereas ( \({V}_{S}\) V S ) increased from 2890 to 3080 m/s. The elastic moduli of the glasses have increased as the concentration TiO2 increased. Including TiO2 in B2O3–SiO2–P2O5–Li2O glasses and investigating its impact on gamma shielding properties through Phy-X simulation provides valuable insights into the glass’s performance in radiation protection. Including TiO2 enhances the proficiency of the shielding due to its influence on the MAC, resulting in better absorption of radiation and hence lower HVL values. The composition-dependent elastic properties of B2O3–SiO2–P2O5–Li2O–TiO2 glasses have significant implications for their potential practical applications.
