【摘要】 采用拉筒法测定了800～950℃范围内Na2WO4 ZnO WO3熔盐体系的表面张力。结果表明:该体系的表面张力与温度成线性关系,随着温度的升高而降低;在同一温度下,熔盐中的阴离子结构随着WO3摩尔含量的增加趋于复杂,表面张力降低,随ZnO摩尔含量的增加趋于简单,表面张力升高;组元ZnO对表面张力的影响比组元WO3大。更多还原

【Abstract】 The surface tensions of Na₂WO₄-ZnO-WO₃ system are measured within the scope of 800～950℃. The results show that the surface tensions are decrease with the temperature rise and the relationship of the surface tensions to the temperature is linear approximately. The anion structure in the molten salt is changed to complexity with WO₃ content rise, to simpleness with ZnO content rise and the surface tensions are decreased or increased. The influence of ZnO on the surface tensions is bigger than WO₃.更多还原
