microstructure development of Ni-YSZ composite materials prepared by gel-precipitation method

摘要

Gel-precipitation from aqueous or methanol solutions of corresponding chlorides was used to obtain nickel oxide - yttria stabilized zirconia powder mixtures. It was shown that both, the course of powder preparation and the composition of the powder mixtures, affect its sinterability and hence its appropriateness as the anodic material in solid oxide fuel cell technology (SOFC) After sintering both phases NiO and YSA are continuous. The continuity of YSZ and Ni phases is Also preserved after reduction.
