防辐射玻璃的改进

IMPROVEMENT ON IRRADIATION PROOF GLASS

在Ｋ２Ｏ（Ｎａ２Ｏ）ＰｂＯ（ＴｉＯ２）ＳｉＯ２（Ａｌ２Ｏ３）系统中，对高能辐射的防护能力可以用Ｃｏ６０γ源检测。玻璃的化学稳定性、折射率、密度、硬度及线膨胀系数的测试研究结果表明：玻璃的防辐射能力不但取决于玻璃的密度及组分的质量吸收系数，而且与玻璃的结构特征有关。根据实验结果，提出了组成和结构对玻璃防辐射能力的综合效应观点。

The irradiation proof ability for high energy radiation of irradiation proof glass in K 2O(Na 2O)PbO(TiO 2)SiO 2(Al 2O 3) system was measured by C o 60γ source.The chemical stability,refractive index,density,micro hardness and linear expansion coefficient were measured by corresponding methods.Results indicate that the ability of irradiation proof of the glass is not only decided by the density and the mass absorption coefficient of the glass but also related to the structural characteristics.According to the experimental results,the synthetical effects of glass composition and structure on irradiation proof ability were proposed.
