High dense cadmium lead-borate glasses: fabrication, physical properties and capability for γ-ray and neutron shields
High dense cadmium lead-borate glasses with nominal compositions of (75-X)B2O3-XPbO-5Na2O-10CdO-10ZnO: X = 5–20 mol% in steps of 5 were fabricated via the melt quenching technique. The physical features and the capability of applying the prepared glasses as γ-ray and fast neutron shields have been investigated. The density (Ds) values increased from 4.820 g.cm−3 to 5.664 g cm−3 as PbO content increased from 5 to 20 mol% in the glass network. The polaron radius (rp) increased, while the field strength (F) reduced as PbO content increased. The boron ion concentration (NB) of the investigated glasses decreased from 2.231 × 1022 (ions.cm−3) to 1.503 × 1022 (ions/cm3). The inter-ionic distance (ri) values increased from 3.551 to 4.051 Ao. Values of the packing density (Pd) decreased from 0.888 to 0.695. The free volume (Vf) enhanced from 2.105 to 6.698 g mol−1 cm−2. The sample BPNCZPb-20 possessed the highest exposure (EBF) and energy absorption (EABF) buildup factors values at 1– 40 MFP among all investigated glasses. The half- value layer (HVLFCS) and the relaxation length (λFCS) values were the lowest for the BPNCZPb-5 glass sample. Therefore, the sample coded as BPNCZPb-20 can be considered as γ-ray shield, but BPNCZPb-5 glass can be used as a neutron shield.
