| Abstract |
| Mechanical features have been investigated to the glass system with the chemical
composition xSrO-10PbO-(90–x)B2O3 with various concentrations of x = 20, 25, 30,
35, 40 and 45 mol%. Based on the Makishima-Mackenzie model, the elastic modulus
has been predicted for the SrPbB glasses. The obtained results illustrate that elastic
moduli reduced with the addition of SrO concentrations in the lead borate glass. The
highest values of Young’s (89.03 GPa), bulk (68.36 GPa), shear (4.69 GPa), and
longitudinal (114.63 GPa) moduli have been detected in the SrPbB20 glass with 20
molar fraction of SrO and low density of 3.29 g.cm–3. The radiation shielding properties
have also been studied for the discussed glasses. Among the shielding parameters,
the transmission factor and the mean free path have been detected according to the
linear attenuation coefficient values which have been simulated utilizing the Monte
Carlo simulation code MCNP5. Successively, the exposure buildup factors and the
energy absorption buildup factor have been predicted using the BXCOM programme
to appreciate the photons accumulation inwards the studied glass material as well
as the effective atomic number (Zeff) and the equivalent atomic number (Zeq). Finally,
it has been concluded that the present synthetical glasses are preferred to be utilized
in various radiation shielding applications.
