摘要
采用传统的熔融冷却法制备了Li2O-Bi2O3-WO3-B2O3系统玻璃,对玻璃的电导率、质量密度和硬度进行了研究。结果表明,在Li2O-Bi2O3-WO3-B2O3系统玻璃中,固定n(Bi)∶n(B)=3∶2,当Li2O摩尔分数保持不变时,随着WO3摩尔分数的增加,玻璃的质量密度增大,硬度减小;当WO3摩尔分数保持不变时,随着Li2O摩尔分数的增加,玻璃的质量密度和硬度先增大后减小,在Li2O摩尔分数为13%时达到最大值,出现了硼反常现象,质量密度最大值为6.6 g/cm3,硬度最大值为401.6 HV。
Glasses in the system Li2O-Bi2O3-WO3-B2O3 were prepared by melt-cooling method. The density, hardness and electrical conductivity of these glasses were investigated. Results showed that set n（Bi） ： n（B）=3 ： 2, when the content of Li2O was fixed, with the content of WO3 increased, the density of the glass increased and the hardness reduced; when the content of WO3 was fixed, with the content of Li2O increased, both the density and the hardness of the glass first increased and then decreased. When the content of Li2O was 13%, the density and hardness of the glass reached the maximum, and the B abnormal phenomenon occured. The maximum of density was 6.6 g/cm^3 , and that of hardness was 401.6 HV.
