摘要: Powders of In2O3–Y2O3“dual stabilized”ZrO2 (IYSZ) were prepared using sol-gel procedures and tested for resistance to destabilization by molten NaVO3 at 700° 900°C. IYSZ powders with stabilizer oxide compositions ranging from 100% down about 50% In2O3 superior 100%-Y2O3-stabilized ZrO2 (YSZ) in destabilization, especially 700°C. Small additions Y2O3 speculated reduce the acidity anion lattice, and, therefore, improve bonding (more acidic than Y2O3) into lattice.
