Synthesis, thermal, optical, mechanical and radiation-attenuation characteristics of borate glass system modified by Bi2O3/MgO

Abstract

This paper provides in-depth experimental validations on the synthesis, optical, thermal, mechanical, and radiation-shielding properties of a novel xBi(2)O(3)-10MgO-(90-x)B2O3, where 20 <= x <= 40 mol %, glass system. The melt quench process is used to prepare all the samples of this glass system, and the amorphous phase is conformed using an X-ray diffraction test. The structure of all the produced glasses is investigated using differential scanning calorimetry investigations. Moreover, we use Makishima-Mackenzie model to compute the elastic moduli, while the FLUKA simulations are employed to assess the radiation-shielding properties of our glass system. Finally, we compared the obtained results of our new glass system with those of standard and previously published glass systems. The obtained results indicated that the crystallization resistance and mechanical qualities of the glass were enhanced as Bi2O3 content increased. Moreover, the linear attenuation factors for the prepare glasses were maximum at 0.1 MeV with the values of 0.1838 cm(-1), 0.1946 cm(-1), 0.2050 cm(-1), 0.2149 cm(-1)and 0.2220 cm(-1) as Bi2O3 content increased from 20 to 40 mol %, respectively. Generally, our prepared glasses show promising properties for optical and radiation applications, especially in medical facilities.
