| 摘 要： | 研究了Na2O-CaO-Al2O3-B2O3-SiO2-TiO2体系分相过程中两相组成的变化。采用扫描电镜测试、能谱分析和X射线衍射等手段对在不同温度下热处理的试样进行测试。实验结果表明,试样发生相分离后,分离成富碱硼相和富硅相,两相的化学组成随分相温度呈现一定的变化。当热处理温度从700℃升高至850℃时,富碱硼相量增加,玻璃分相程度增大。分相温度较低时,富碱硼相中的网调整氧化物只有氧化钙,而网调整氧化物氧化钠集结在富硅相中。随分相温度的升高,氧化钙仍保持在富碱硼相中,而氧化钠则由在富硅相中集聚逐步转移至在富碱硼相中。在分相过程中二氧化钛在分相界面处集聚并析出。

| Abstract: | The changes of two-phase compositions in the phase separation process of Na2O-CaO-Al2O3-B2O3-SiO2-TiO2 system was studied.Samples treated under different temperatures were tested by using SEM examination,energy spectrum analysis,and X-ray diffraction etc..Results showed that after the phase separation,the system was separated into boron/alkali-rich phase and silicon-rich phase;the chemical compositions of the two phases had a definite relation with the changes of phase separation temperatures.When the heat ... |
