  • 本文用热学分析、高温和室温X射线衍射分析、红外吸收光谱等方法研究了NaBO2-B2O3体系玻璃的形成、热稳定性和晶化机制。这一体系十分容易形成稳定的非晶玻璃,晶化过程与非晶的宏观状态有关。块状玻璃的晶化温度比非晶粉末高。部分成份晶化后形成不同的物相,熔点也不同。晶化产物的晶体结构类似于玻璃的结构。NaBO2-B2O3体系的电导率用交流阻抗直接测量法测定。玻璃态的电导率比晶态试
    The formation, thermal stability and crystallization mechanism of glasses in NaBO2-B2O3 system have been studied by means of thermal analysis, X-ray powder diffraction at high and room temperatures, and IR absorption spectra. The stable glasses are formed easily in this system. The crystallization processes are related to macroscopic state of samples. The crystallization temperature of bulk glasses is higher than that of amorphous powders. A part of components crystallizes as different phases. They melt directly at different temperatures. The crystal structure of crystallization products is close to glass structure.The ionic conductivity in NaBO2-B2O3 system was determined by ac impedance method. The conductivity of glasses are 2-3 orders higher than that of crystals with the same composition, while the activation energy of glasses lower than that of crystalline state for the same composition.
