Supplemental Literature Review: Section III

Ho-Li (Holmium-Lithium) H. Okamoto

Reference

The Ho-Li phase diagram was unknown in [Massalski2]. Figure 1 shows the Ho-Li phase diagram constructed based on a schematic phase diagram and a table of invariant reaction temperatures and compositions given in [1998Gan]. Table 1 shows Ho-Li crystal structure data.
