Markova-Velichkova, R. Iordanova, A. Stoyanova, Y. Dimitriev, D. Klissurski] Melt quenching technique was applied to study tendency for phase formation and amorphization in the MoO3-ZrO2-V2O5 system. By X-ray diffraction were detected the main crystalline phases separated during the quenching: Zr(MoO4)2, V2MoO8, (Mo0.3V0.7)2O5, V0.95Mo0.97O5 but in a wide concentration range the dominant crystalline phase was monoclinic ZrO2. The average particle sizes of the obtained crystal phases were in the range 30-50nm. A narrow glass formation area was situated, near MoO3-V2O5 side. The glass-crystalline samples were obtained in the MoO3- and V2O5-rich compositions. The phase formation was proven by IR analysis also. IR data showed that the main structural units built up the glass network are corner shared VO5 and MoO6 groups while in the corresponding crystal V2MoO8 phase MeO6 (Me=V, Mo) octahedra are corner and edge shared (band at 580cm−1).
