Abstract

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 (D_s) 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 (r_p) increased, while the field strength (F) reduced as PbO content increased. The boron ion concentration (N_B) of the investigated glasses decreased from 2.231 × 10²² (ions.cm⁻³) to 1.503 × 10²² (ions/cm³). The inter-ionic distance (r_i) values increased from 3.551 to 4.051 A^o. Values of the packing density (P_d) decreased from 0.888 to 0.695. The free volume (V_f) 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 (HVL_FCS) and the relaxation length (λ_FCS) 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.

高密度铅硼酸镉玻璃：制造、物理性质以及用于γ射线和中子屏蔽的能力

通过熔体淬火技术制备了高密度铅硼酸镉玻璃，其标称成分为(75-X)B2O3-XPbO-5Na2O-10CdO-10ZnO：X = 5-20 mol%，以 5 为单位。研究了所制备玻璃的物理特性以及将其用作γ射线和快中子屏蔽的能力。随着玻璃网络中氧化铅含量从 5 摩尔%增加到 20 摩尔%，密度（Ds）值从 4.820 克/厘米-3 增加到 5.664 克/厘米-3。随着氧化铅含量的增加，极子半径（rp）增大，而场强（F）减小。所研究玻璃的硼离子浓度（NB）从 2.231 × 1022（离子.cm-3）降至 1.503 × 1022（离子/cm3）。离子间距 (ri) 值从 3.551 Ao 增加到 4.051 Ao。堆积密度 (Pd) 值从 0.888 降至 0.695。自由体积（Vf）从 2.105 g mol-1 cm-2 增加到 6.698 g mol-1cm-2。在所有研究的玻璃中，BPNCZPb-20 样品在 1- 40 MFP 时的暴露（EBF）和能量吸收（EABF）堆积因子值最高。BPNCZPb-5 玻璃样品的半值层（HVLFCS）和弛豫长度（λFCS）值最低。因此，编码为 BPNCZPb-20 的样品可视为γ射线屏蔽，而 BPNCZPb-5 玻璃则可用作中子屏蔽。
