•The generated phases at the V-slag surface, the CaO surface are Ca2V2O7, Ca2V2O7 and Ca3V2O8, respectively.•The generated phases at the V-slag surface where the diffused Ca has not reached are mainly consisted of Fe2O3 and Mn2O3.•New method is proposed to determine the Matano surface and calculate...
