Powders of In[sub 2]O[sub 3]-Y[sub 2]O[sub 3] dual stabilized ZrO[sub 2] (IYSZ) were prepared using sol-gel procedures and tested for resistance to destabilization by molten NaVO[sub 3] at 700 and 900 C. IYSZ powders with stabilizer oxide compositions ranging from 100% down to about 50% In[sub 2]O[sub 3] were superior to 100%-Y[sub 2]O[sub 3]-stabilized ZrO[sub 2] (YSZ) in resistance to destabilization, especially at 700 C. Small additions of Y[sub 2]O[sub 3] were speculated to reduce the acidity of the ZrO[sub 2] oxide anion lattice, and, therefore, improve bonding of In[sub 2]O[sub 3] (more acidic than Y[sub 2]O[sub 3]) into the ZrO[sub 2] lattice.
