摘要
利用传统的熔融冷却法制备了轻稀土掺杂的Na2O-CaO-SiO2玻璃,研究了轻稀土掺杂对Na2O-CaO-SiO2玻璃的密度和化学稳定的影响。结果表明:轻稀土掺杂对Na2O-CaO-SiO2玻璃的密度具有明显的增大作用;轻稀土掺杂显著地提高了Na2O-CaO-SiO2玻璃的耐水性,氧化镧和氧化钕改善了Na2O-CaO-SiO2玻璃的耐酸和耐碱性,而氧化铈使Na2O-CaO-SiO2玻璃的耐酸和耐碱性变差。
Na2O-CaO-SiO2 system glass doped with different light rare earths were prepared by melting-quenching, the effects of light rare earths on the chemical durability and density of Na2O-CaO-SiO2 system glass were investigated. The results show that light rare earths increase considerably the density of Na2O-CaO-SiO2 system glass, doping light rare earths has important effect on the water resistance of glass, the effects of La2O3 and Nd2O3 on the acid and alkali resistance of glass are positive, however, the effect of CeO2 is negative.
