Data for: Phase equilibria and thermodynamic evaluation of Ti-V-O system in air

However, SEM-EDS data did not compare well to reported EPMA data in the manuscript, especially phase data of the Ti-V-O slag. We believe that the overlapping of V and Ti X-ray emission peaks might have contributed why SEM-EDS data did not compare well to EPMA data. 2.) The data from EPMA were normalized and included in the thermodynamic assessment of Ti-V-O system in air.
