中文摘要：

通过添加BaO增加了铝酸钙玻璃的成玻能力， 确定了CaO鄄BaO鄄Al2O3三元系统的成玻区域：25～45 mol%的 Al2O3，45～65mol%的 CaO， 0～18 mol%的 BaO， 在成玻区域内采用 Hruby 值研究 Al2O3/CaO 值和 BaO 含量对系统成玻能力的影响，发现当 Al2O3/CaO 值为 0.60、BaO 含量为 8 mol%时，系统的成玻能力最强。 以成玻能力最好的 56CaO鄄8BaO鄄36Al2O3组成为基础，将真空烧结后几乎不含“水”的玻璃配合料分别在大气环境下、 干燥氮气保护以及干燥氮气保护＋CCl4搅拌等 3 种不同的条件下进行熔制，分析玻璃的红外透过光谱和残余水分含量。 结果表明：采用干燥氮气保护＋CCl4搅拌的方法，7mm 玻璃在 2.9滋m 的透过率接近 84%，残余水分含量仅为 0.0037，基本消除了 OH-1的影响。

英文摘要：

Glass-forming ability of calcium aluminate glasses is improved with the actlition of BaO, glass- forming region of CaO-BaO-Al2O3 ternary system is identified which is the area with content of Al2O3 between 25 mol% and 45 mol%, CaO between 45 mol% and 65 mol% and BaO between 0 mol% and 18 mol%. According to the study of ifrcdo, value. Influences of the ratio of content of Al2O3 and CaO（A/C） and the content of BaO on glass-forming ability were discussed based on the value of Hmby. It was found that glass-forming ability of 56 CaO-8 BaO-36 Al2O3 is best when the value of A/C is 0.60 and the content of BaO is 8 mol%. Batches without any water sintered in normal air inthe cicwstance, protected by dry nitrogen as well as stirred with COl4 respectivelf into, 30 as to detect as IR-transmittance spectrum and investigated by residual contents of water namely B（OH）. which indicated that the transmittance at 2.9 μm is nearly 84% and the residual B（OH） is 0.003 7. It was demonstrated that hydroxyl was almost removed by stirring with CCI4 while protected by dry nitrogen.
