- Type of method:
- thermal analysis
- Decomposition:
- yes
- Decomp. temp.:
- 745 °C
- Sublimation:
- no
- Conclusions:
- Aluminium vanadium tetraoxide melts incongruently at 745 °C, releasing the solid α-Al2O3.
Reference
The verification of the Al2O3 -V2O5 phase diagram has proved that at the content of ~8 mol % Al2O3 and ~92 mol % V2O5, the components heated to ~ 640 °C form a eutectic: AlVO4 + V2O5. AlVO4 melts incongruently at 745 °C, releasing the solid α-Al2O3.
Description of key information
Aluminium vanadium tetraoxide melts incongruently at 745°C.
Key value for chemical safety assessment
