摘要: 以BaO-TiO2 -SiO2 -Rm On玻璃为研究对象,用通常的熔融法熔制,当SiO2 的质量分数分别为15%,12% 和10% ,BaO与TiO2 的质量分数之和分别为73%,76% 和78%时,改变BaO和TiO2,的质量比,可得到折射率在1.833 8~1.9189之间的系列大块玻璃.用WYV-V型V棱镜测量玻璃的折射率,用阿基米德法测定玻璃的密度,结果表明,该类玻璃的折射率随BaO与TiO2 的质量比增大而减小,密度随BaO与TiO2 的质量比增大而先增后减,当BaO与TiO2 的质量比在2.077附近时密度出现最大值.文中最后采用加和性规律和极化率概念对实验结果进行了定性分析.

Abstract:

With BaO-TiO2 -SiO2 -Rm On glasses as the research object,large-sized titanate glasses with a refrac-tive index of 1.8338~1.9189 were prepared by the melting method.In the preparation process,the mass fractions of SiO2 were respectively controlled at 15%,12% and 10%;the sums of the mass fractions of BaO and TiO2 were respectively controlled at 73%,76% and 78% with different ratios of BaO to TiO2.The refractive indexes and the
densities of the prepared glasses were respectively measured by using a W YV-V prism and by means of the Archi-medes method.The results show that,with the increase of the mass ratio of BaO to TiO2,the refractive indexes of the glasses decrease,while the densities first increase and then decrease.At the mass ratio of 2.077,the density shows a maximum .The above-mentioned results were finally qualitatively analyzed according to the rules of additive and polarization.
