摘　　要：采用高温熔融的方法制备R2O-CaO-Al2O3-B2O3-SiO2-P2O5多元系统乳浊玻璃,运用FT-IR、SEM和XRD对玻璃的结构和分相进行了分析,测试了玻璃的热膨胀曲线、耐水性、显微硬度和釉烧性能。研究了以MgO-CaO取代Na2O对玻璃乳浊程度以及其结构与性能的影响。结果表明,随着Na2O含量的降低和MgO-CaO含量的增加,玻璃的乳浊程度逐渐降低最后趋于透明,热膨胀系数表现出递减的趋势,而转变温度和软化温度呈逐渐升高的趋势;化学稳定性优异且逐渐增强,玻璃水解等级均为一级。The R2O-CaO-Al2O3-B2O3-SiO2-P2O5 system glass was prepared by high temperature melting method. The structure and phase separation of the glass were analyzed by FT-IR, SEM and XRD. The thermal expansion curve, chemical stability, microhardness and glaze performance of the glass were also tested. The effect of substituting MgO-CaO for Na2O on the opacity and structure and properties of glass were studied. The results showed that the opacity of the glass gradually decreases and finally becomes transparent with the decrease of Na2O content and the increase of CaO-MgO content. The thermal expansion coefficient showed a decreasing trend, while transition temperature and softening temperature showed an increasing trend on the contrary. The chemical stability of the glass is excellent and gradually strengthened, and the hydrolysis grade is in the first order.
