“…The values of (K MM ) (calculated according to Makishima and Mackenzie model [43]) are found to increase with the addition of Pb ions into the bismuthate glass network. This confirms that the incorporation of Pb ions with the tetrahedral oxidation states that filled the interstices which led to the increment of the Packing density (V t ) values and number of bonds per unit volume n b (calculated using bond compression model [41]) and decreased the average atomic ring size (l), confirming the increase in bridging oxygens. The results are in accordance with the increase in the theoretically obtained elastic moduli that represented in Tables 3 and 4, indicating the increased rigidity of the glass system with increasing Pb ions from 3 to 10 mol percentage content [48][49][50].…”

Kinetic, mechanical properties of xPbO-(10-x)Er 2 O 3 -90Bi 2 O 3 : x = 3 (BEP-3), 5 (BEP-5), 7 (BEP-7), 9 (BEP-9), and 10 (BEP-10) mol% glass system were investigated experimentally utilizing the pulse-echo technique and theoretically via bond compression and Makishima and Mackenzie models. Radiation shielding capacity of the investigated BEP-glasses was also evaluated via Phy-X/PSD code. The longitudinal and shear ultrasonic wave velocities were increased with the increase in PbO content in BEPglasses. Values of the elastic moduli, longitudinal modulus, shear modulus, bulk modulus, and microhardness, for BEP-glasses were enhanced when the PbO content increased from 3 to 10 mol % content. There was good agreement between the obtained values of experimental and theoretical values of elastic moduli. The maximum mass attenuation coefficient

“…e ΔT value of the TPZBF-7 sample is 59°C, which is a small value in tellurite glass. It can also be seen from Figure 5 that the first crystallisation peak of the glass is next to the glass transition temperature peak, so the series of glasses are relatively easy to crystallize [18][19][20].…”

The tellurite 60TeO2-20PbO-(20-x)ZnO-xBaF2 (x = 1, 3, 5, 6, 7, 9, and 11) series glass samples were prepared. The samples’ SEM, XRD, DSC, density, refractive index, and absorption spectra were tested. A self-made optical platform was used to measure and calibrate the refractive index. The relationship between glass composition and crystallinity was discussed. The effects of density, molar refractive index, and metal standard value on the refractive index of glass samples were studied. The results showed that TPZBF glass has a high refractive index, and the refractive index increases with the increase in BaF2 content.

“…Formerly, semiconducting glasses have been extensively studied via two categories: oxide glasses and chalcogenide glasses. The chalcogenide glasses modified with transition metal oxides (TMOs) have unique structure, physical, optical, mechanical, electrical, thermal, semiconducting, and radiation shielding features [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…From our best acquaintance that tellurite, phosphate, borate, and silicate-based glass networks are the best glass candidates due to their excellent characteristics, for example (low cost and ease molding, low melting points, high transparency, and good thermal stability) [8][9][10]. Moreover, TeO2 based glasses have gained more focusing from many researchers and investigators due to their unique features such as high linear and nonlinear refractive indices and good shield for radiations [11,15,[19][20][21][22].…”

Effects of antimony trioxide (Sb2O3) on neutron and gamma-radiation shielding parameters of tellurite vanadio-antimonite glasses with compositions 40TeO2-(60-x)V2O5-xSb2O3: 0 ≤ xSb2O3 ≤ 10 mol% coded as (TVS0-TVS10) were investigated. The mass attenuation coefficients (MAC) were evaluated using the Monte Carlo simulation code (MCNP-5) and WinXcom program for photon energies in the range of 15 keV to 15 MeV. The SRIM program was used to compute the stopping power and projected range of the charged particles, such as proton and alpha particles, on the investigated glass samples. Based on the theoretically evaluated MAC, some shielding parameters were computed, such as linear attenuation coefficient, electric cross-section, atomic cross-section, effective atomic number, half-value thickness (HVT), and the mean free path. The EXABCal program was applied to predict the level of the photons accumulation in the investigated glass samples (buildup factors). The effective cross-section for fast neutrons was computed theoretically based on the fast neutron effective removal cross-section (ΣR ) for the constituting components. Results revealed that the maximum values of MAC exceed in the range between 28.9-31.3 cm2/g with increasing the Sb2O3 substitution ratio between 0-10 mol %, respectively. In contrast, the HVT values decrease with an increase in the increment of Sb2O3 rate. The maximum (ΣR) was obtained for glass coded TVS0 among the investigated glasses. Results concluded that the higher Sb2O3 concentration in TVS glasses leads to an increase in their capability to apply in several radiation shielding applications.
