The compounds Li2MoO4 and Li2WO4 have the phenacite structures with almost
the same lattice constants. It is expected and was actually reported that t
he Li2MoO4-Li2WO4 quasi-binary system forms a complete solid solution. In t
he present study, however, we found by differential thermal analysis (DTA)
that the system actually forms a partial solid solution with the peritectic
reaction. (C) 2000 Elsevier Science B.V. All rights reserved.
