Mechanical, gamma-ray buildup factors, and neutron-sensing properties of cupric alumino lithium borate glasses of the form xCuO–(20−x)Li2O–60B2O3–20Al2O3: x = 0.0, 0.2, 0.4, 0.8, 1.2, 1.6, 2.0, and 2.4 mol% have been examined. The bond compression values of Young’s (EB–C) elastic modulus were enhanced from 94.739 to 98.959 GPa, from 36.267 to 37.909 GPa for shear (SB–C), and from 129.739 to 135.081 GPa for longitudinal (LB–C). Poisson’s ratio (σB–C) for BLiAlCu glasses was decreased from 0.3061 to 0.3051. Makishima–Mackenzie elastic moduli showed that the replacement of CuO by Li2O leads to a slight increase of values of (EM–M) from 54.269 to 55.321 GPa, (KM–M) from 31.931 to 33.448 GPa, and (SM–M) from 22.301 to 22.592 (GPa). Poisson’s ratio (σM–M) for glasses was increased from 0.216 to 0.224. The position of the EABUF and EBUF peaks vary with depth and chemical composition of the glasses; however, all the peaks appear within 0.08 and 0.15 MeV and shifting to higher energy as depth increases. Comparing the BUFs for the different glasses, it is apparent that BUFs decreases with increase in Cu content of the glass system at low energies. Hence, (BUFs)BLiAlCu0.0 > (BUFs)BLiAlCu0.4 > (BUFs)BLiAlCu0.8 > (BUFs)BLiAlCu1.2 > (BUFs)BLiAlCu1.6 > (BUFs)BLiAlCu2.0 > (BUFs)BLiAlCu2.4 at 0.015. The increase of CuO content of the glasses leads to improve in the fast neutron removal capacity.

B2O3–Al2O3–Li2O–CuO 玻璃的机械、光子积累因素和中子传感特性的研究

x CuO–(20− x )Li 2 O–60B 2 O 3 –20Al 2 O 3形式的铜铝硼酸锂玻璃的机械、伽马射线累积因子和中子传感特性:x  = 0.0, 0.2,已检测 0.4、0.8、1.2、1.6、2.0 和 2.4 mol%。杨氏(E B–C)弹性模量的粘合压缩值从 94.739 GPa 提高到 98.959 GPa,剪切(S B–C)从 36.267 GPa 到 37.909 GPa,纵向(L B–C)从 129.739 GPa 到 135.081 GPa . 泊松比 ( σ B–C) BLiAlCu 玻璃从 0.3061 降低到 0.3051。Makishima–Mackenzie 弹性模量表明,Li 2 O取代 CuO导致 ( E M–M ) 从 54.269 GPa 增加到 55.321 GPa,( K M–M ) 从 31.931 GPa 增加到 33.448 GPa,以及 ( S M–M ) 从 22.301 到 22.592 (GPa)。泊松比 ( σ M–M) 眼镜从 0.216 增加到 0.224。EABUF 和 EBUF 峰的位置随玻璃的深度和化学成分而变化;然而,所有峰值都出现在 0.08 和 0.15 MeV 之间,并且随着深度的增加而转移到更高的能量。比较不同玻璃的 BUF,很明显,在低能量下,BUF 随着玻璃体系中 Cu 含量的增加而减少。因此,(BUFs) BLiAlCu0.0  > (BUFs) BLiAlCu0.4  > (BUFs) BLiAlCu0.8  > (BUFs) BLiAlCu1.2  > (BUFs) BLiAlCu1.6  > (BUFs) BLiAlCu2.0  > (BUFs) BLiAlCu2.4在 0.015。玻璃中CuO含量的增加导致快中子去除能力的提高。
