Influence of Alumina Platelets on the Mechanical Strength of Porous Zirconia Tape
The improvement of the mechanical strength of a porous anode support (NiO/8YSZ) induced by the addition of 5 to 10v% of alumina platelets to the basic composition was studied. The results obtained proved that the addition of 10v% alumina platelets, Placor 6, to the NiO/8YSZ composition improved the bending strength of the sintered material by nearly 20%, without any significant effect on the electrochemical performance. Changes in the processing procedure also had a strong influence on the mechanical strength, which resulted in the mechanical strength being increased to more than 100 MPa.
