Abstract In this paper,the activity coefficient of MnO in liquid blast-furnace-type slagshas been evaluated as a function of the basicity ratio,calculated according to a newformula previously proposed by the author,with reference to pure solid MnO as thestandard state.The data of Stukel and Cocubinsky,and Filer and Darken havebeen used as the basis of this calculation.The results of this paper together withthe α_(CaO) values evaluated in a previous paper are discussed from the standpoint ofionic nature of slags.
