Hot corrosion behavior of neodymium magnesium hexaaluminate by vanadium pentoxide in air.

Highlights: [•] Hot corrosion products are different at temperatures ranging from 650 to 950°C. [•] At 650°C, the main corrosion products are AlVO4 and NdVO4. [•] At 750°C, V2O5 reacts with NdMgAl11O19 to form NdVO4, MgV2O6, AlVO4 and alumina. [•] At 850°C, the corrosion products consist of θ-Al2O3, NdVO4 and MgAl2O4. [•] At 950°C, the corrosion products are composed of α-Al2O3, NdVO4 and MgAl2O4. [ABSTRACT FROM AUTHOR]
