摘　　要：研究了空调压缩机接线端子用SiO2-R2O3-R2O-RO系铁封玻璃中碱金属氧化物总摩尔量不变情况下,Na2O、K2O比例变化对玻璃理化性能的影响。结果表明:随K2O/(Na2O+K2O)比值的增大,玻璃的膨胀系数逐渐增大,软化温度逐渐升高,耐水化学稳定性及体积电阻率提高,玻璃流散性和浸润性逐渐变差。混合碱效应对SiO2-R2O3-R2O-RO系铁封玻璃的膨胀系数、软化温度、体积电阻率及耐水化学稳定性变化趋势产生较大影响。The influence of alkali metal oxides on the physical and chemical properties of SiO2 -R203 -R20- RO system iron -sealing glass was investigated. The results indicated that the glass fluxion and wettability deteriorated and chemical durability, volume resistivity, thermal expansion coefficient and softening temperature increased gradually with the increasing of the K20 / （ Na2O ＋ K2 O） ratio. The mixed alkali effect had a great impact on the property trend of α, Tf, ρv and chemical durability of the SiO2 - R2O3 - R2O - RO system iron - sealing glass.
