Electrical Conductivity of ZrO[sub 2]-Sc[sub 2]O[sub 3] Doped with HfO[sub 2], CeO[sub 2], and Ga[sub 2]O[sub 3]

The effects on the electrical conductivity and the crystalline structure of the addition of and to with 11 mol % (11ScSZ) have been examined. 11ScSZ has the rhombohedral structure and is transformed to cubic structure at 580°C. The cubic phase was stabilized at room temperature by the addition of about 6 mol % and 2 mol % to 11ScSZ. No such effect was observed by addition of The electrical conductivity of 11ScSZ was depressed by the addition of and © 2001 The Electrochemical Society. All rights reserved.
