This work aimed to investigate optical, structural and physical properties of newly developed Dolomite reinforced borate glasses via experimental and simulation techniques. Accordingly, a glass composition (40-x) B2O3–40PbO–20ZnO-xDolomite of various compositions of Dolomite [CaMg(CO3)2] where, (x = 0.0, 1.0, 2.0, 3.0 and 4 wt%) were synthesized by using melt-quenching method. The Dolomite [CaMg(CO3)2] doped glasses encoded DG-0, DG-1, DG-2, DG-3 and DG4 with different compositions are prepared. The optical properties of prepared dolomite glasses have been measured. The results show an enhancement of the absorbance as dolomite contents increases. Using gamma spectroscopy, the radiation shielding properties have been measured. Moreover. Comparatively higher density (DG-4 = 3.868 g/cm3), greater μ, μm and lower T1/2, λ values achieved for (40-x) B2O3–40PbO–20ZnO-xDolomite glass indicated it as a better gamma shield. Besides, the calculated Radiation protection efficiency at 1 cm observe that the (40-x) B2O3–40PbO–20ZnO-x[CaMg(CO3)2] sample has commensurately greater and ranged (14.11565 at 2.614 MeV and 98.35382 at 0.081 MeV). The results observed that Dolomite addition improves the gamma protection ability of lead-zinc borate glasses. The results indicate that the highest Dolomite addition encoded DG-4 has the best shielding competence with measurable physical and optical properties.

新开发的用于核辐射屏蔽的白云石增强硼酸盐玻璃的合成,光学,结构和物理性质:一项实验和模拟研究

这项工作旨在通过实验和模拟技术研究新开发的白云石增强硼酸盐玻璃的光学,结构和物理性能。因此,玻璃组成(40-x)B 2 O 3 –40PbO-20ZnO-x白云石[CaMg(CO 32 ]的各种组成的白云石,其中(x = 0.0、1.0、2.0、3.0和4 wt%)通过熔融淬火法合成。白云石[CaMg(CO 32制备具有不同组成的掺杂的编码为DG-0,DG-1,DG-2,DG-3和DG4的玻璃。已经测量了制备的白云石玻璃的光学性质。结果表明,随着白云石含量的增加,吸光度增加。使用伽马能谱法测量了辐射屏蔽性能。而且。相对较高的密度(DG-4 = 3.868 g / cm 3),较大的μ,μm和较低的T 1/2,(40-x)B 2 O 3 –40PbO-20ZnO-x白云石玻璃的λ值表示为更好的伽玛屏蔽。此外,计算得出的1 cm辐射防护效率观察到(40-x)B 2 O 3 –40PbO-20ZnO-x [CaMg(CO32 ]样品具有相称更大的范围(在2.614 MeV时为14.11565,在0.081 MeV时为98.35382)。结果观察到白云石的添加提高了硼酸铅锌玻璃的γ保护能力。结果表明,最高的白云石加成编码的DG-4具有最佳的屏蔽能力,并且具有可测量的物理和光学性质。
