Abstract:
利用ＺｒＯ_２固体电解质氧浓差电池测定了电渣重熔用ＣａＦ_２＋Ａｌ_２Ｏ_３和ＣａＦ_２＋Ａｌ_２Ｏ_３＋ＣａＯ系熔渣的氧渗透率，考察了熔渣成分及温度对熔渣传氧性能的影响．在１６７３—１８７３Ｋ和０．１ＭＰａ的氧气氛下，侧得这两个渣系熔渣的氧渗透率分别为１×１０－（２０）—６×１０－（１９）和１×１０￣（２１）—５×１０￣（１８）ｍｏｌＯ_２·ｃｍ￣（－１）·ｓ￣（－１）；随ＭｎＯ_２，Ｆｅ_２Ｏ_３，Ｃｒ_２Ｏ_３，ＴｉＯ_２，ＣａＦ_２含量和碱度（ＣａＯ／ＳｉＯ_２）的增高，熔渣的氧渗透率增大，ＭｎＯ_２和Ｆｅ_２Ｏ_３的影响尤为显著；随温度的升高，熔渣的氧渗透率增大，且可按速率过程来处理ＣａＦ２基多元复杂熔渣的传氧过程。
