The phase diagram of the ZnO-Cr2O3-V2O5 system in subsolidus area has been elaborated by DTA and XRD methods. It has been shown that the system consists of eight subsidiary subsystems in which there coexist in equilibrium three solid phases in each case. The melting temperatures of these subsystems have also been determined. (C) 2010 Elsevier B.V. All rights reserved.
