引言钍在水溶液中一般以 Th~(4+)状态或以其它络离子形式存在。在熔态时,根据等对 ThCl_4熔体的研究,他认为:由于钍离子半径较小(1.04),而电荷较大,故可能在熔体中不是以 Th~(4+)状态存在。此外,ThCl_4熔体的当量电导为16Ω~(-1)Cm~2,比典型的离子型熔体(如碱金属及碱土金属氯化物的熔体)的电导为小;但又较分子型熔体(如 BeCl_2)的电导为大,故等认为 ThCl_4熔体可能为介于这两类型
Introduction Thorium in aqueous solution generally Th ~ (4 +) state or in other complex ion form. In the molten state, according to the study of ThCl4 melt, he thinks: Due to the smaller radius of thorium ion (1.04) and the larger charge, it may not exist in the melt in the Th4 + state. In addition, the equivalent conductance of ThCl 4 melt is 16 Ω -1 Cm 2, which is smaller than that of typical ionic melts such as those of alkali and alkaline earth chlorides. (Such as BeCl_2) conductivity is large, so think so that ThCl 4 melt may be between these two types
