Difference in radiation effects of sodium Borosilicate Glass and vitreous silica with ions
Journal of Non-crystalline Solids, 2019Co-Authors: M. Guan, Xiaoyang Zhang, K.j. Yang, T.t. Wang, X. Du, T.s. Wang, H.b. PengAbstract:Abstract Borosilicate Glass is used to vitrify high-level radioactive waste. Radiation effects on Borosilicate Glass have been studied extensively. Sodium Borosilicate Glass samples with compositions of 67.3% SiO2, 16.7% B2O3 and 16% Na2O in molar percent and vitreous silica were irradiated with multi-energy and single-energy Xe ions. After irradiation, hardness and modulus of both materials were accessed by nanoindentation. Volume change in two materials was evaluated using AFM. The hardness, modulus and volume change of both sodium Borosilicate Glass and vitreous silica varied fast and then saturated with the dose. The trends of both modulus and volume change with the dose for sodium Borosilicate Glass were respectively opposite to those for vitreous silica. The relative hardness variation of sodium Borosilicate Glass was −35%, and that of vitreous silica was about −10%. Difference in radiation effects between the sodium Borosilicate Glass and vitreous silica suggested that hardness decrease in sodium Borosilicate Glass irradiated with ion might be induced not only by transformation of silicate network but also by the transformation of boron network.

Variation of hardness and modulus of sodium Borosilicate Glass irradiated with different ions
Nuclear Instruments & Methods in Physics Research Section B-beam Interactions With Materials and Atoms, 2018Co-Authors: H.b. Peng, M. Guan, Xiaoyang Zhang, X. Du, Wei Yuan, B.h. Duan, T.s. WangAbstract:Abstract Borosilicate Glass with characteristics of high thermal, mechanical and chemical resistance has plenty of applications. As one of the candidates who are possible to vitrify high level radioactive waste, the Borosilicate Glass has been studied extensively. The Borosilicate Glass was added with sodium to increase electrical conductivity and decrease viscosity. The tolerance of sodium Borosilicate Glass on irradiation is important to vitrification. In this work, the sodium Borosilicate Glass samples were irradiated with different ions. The dependence of hardness and modulus on irradiation dose was studied. A semi-empirical formulation was proposed. Possible reasons for the change of modulus and hardness were discussed.

Effect of irradiation on hardness of Borosilicate Glass
Journal of Non-crystalline Solids, 2016Co-Authors: H.b. Peng, K.j. Yang, Wei Yuan, B.h. Duan, Hao Chen, D. Yang, Liang Chen, T.s. WangAbstract:Abstract Borosilicate Glass samples were irradiated by Xe and Kr ions with different fluences. The nanoindentation hardness of samples was measured. For samples irradiated by Xe and Kr ions, the hardness variation dropped with the irradiation dose in displacement per atom. The experimental results are consistent with those of other studies. A rough model was proposed to explain the results of this study and those of others.

ultrashort laser pulse induced nanogratings in Borosilicate Glass
Applied Physics Letters, 2014Co-Authors: Felix Zimmermann, Anton Plech, Soren Richter, Andreas Tunnermann, Stefan NolteAbstract:We report on nanogratings inscribed by repetitive femtosecond laser pulses into the bulk of Borosilicate Glass. The irradiation produces small nanopores (10–20 nm thick) which start to self-organize in gratings as well as elongated sheets of up to 400 nm length. A quantitative description of the grating structure and its development are obtained by a combination of focused ion beam milling, scanning electron microscopy, and small angle X-ray scattering (SAXS). The SAXS partial invariant of the thin sheets is found to correlate well with the measured optical retardance. Compared to fused silica nanogratings Borosilicate Glass shows a much smaller retardance due to re-annealing of pores. In addition, the nanograting period strongly deviates from the well-known λ/2n prediction. We could observe periods down to 60 nm (at an inscribing wavelength of 800 nm). This has not been observed yet in other Glasses.

The effect of neutron and mixed gamma and neutron irradiation on the solar properties of Borosilicate Glass
Research on Chemical Intermediates, 2014Co-Authors: Nilgun Baydogan, A. Beril TugrulAbstract:Neutron and mixed gamma and neutron irradiation, at different absorbed doses, of Borosilicate Glass with four different chemical compositions was conducted to investigate the effects on the solar properties of the Glass. Irradiation was performed in the tangential beam tube and central thimble of a nuclear reactor. The effect of thermal and epithermal neutrons on such solar properties as secondary heat-transfer factor, solar factor (the total solar energy transmittance), and shading coefficient of the Borosilicate Glass were investigated to determine the effect on the solar properties of Borosilicate Glass, because of its neutron absorbance property. © 2012 Springer Science+Business Media Dordrecht.

Effect of Tin Penetration on Surface Crystallization of Borosilicate Glass
Journal of Wuhan University of Technology, 2010Co-Authors: Liu QingAbstract:Tin ions may penetrate into Borosilicate Glass surface layer when they were produced by float technics.Surface properties were changed by these tin ions.In this article,the effect of tin penetration on surface crystallization of Borosilicate Glass was researched using optical microscopes and XRD etc.instruments.The difference of crystallization between two surfaces,the surface contacting with tin and the surface no-contacting with tin,were compared.The results indicate there were cristobalites on surface of Glass after heat treatment at 750 ℃.The amount of cristobalite on the surface contacting with tin were more than another surface.As a result,tin penetration do not aggravate the surface crystallization of Borosilicate Glass.

Study on Tin Penetration into Bottom Surface of Float Borosilicate Glass
Glass & Enamel, 2007Co-Authors: Liu QingAbstract:Using a special mini-graphite tin bath to simulate the float process of float Borosilicate Glass,the tin penetration profiles in different temperature area from 1 250 ℃ to 650 ℃ were studied by EPMA/EDS.It was found out that tin diffused into the Borosilicate Glass with a total depth of 40μm.Tin ion diffused towards the deeper layer in the Borosilicate Glass under the higher temperature and only entered the superficial layer under the lower temperature.In the whole float processes,the tin penetration profiles showed a tin hump,but the tin hump disappeared at the temperature at outlet of tin bath.
