摘    要:采用差式扫描量热法(DSC)和热机械分析(TMA)方法研究了P2O5-SiO2-Na2O-Al2O3玻璃系统的热力学性质,探讨了磷酸盐玻璃中不同二氧化硅含量对其特征温度、热膨胀系数的影响、研究表明,随着SiO2的增加,玻璃转变温度Tg及玻璃软化温度Tf逐渐升高,热膨胀系数逐渐降低。

关 键 词:磷酸盐玻璃  二氧化硅  热力学性质

Abstract:The thermodynamic properties of P_2O_5-SiO_2-Na_2O-Al_2O_3 glass system were investigated by means of differential scanning calorimetry and thermo-mechanical analysis. The characteristic temperature and the thermal expansion coefficient of the system with different SiO_2 contents were then discussed. The results indicate that,with the increase in SiO_2 content,the transition temperature (T_g) and soft temperature (T_f) of the glass increase accordingly,while the thermal expansion coefficient decreases.
Keywords:phosphate glass  silicon dioxide  thermodynamic property
