POROUS LANTHANUM MANGANITE SINTERED BODIES AND SOLID OXIDE FUEL CELLS

摘要

A porous sintered body is composed mainly of lanthanum manganite in which a part of lanthanum atoms at A-sites of the lanthanum manganite are substituted by atoms of a metal selected from the group consisting of alkaline earth metals and rare earth metals. The dimensional shrinkage amount of the porous sintered body in heat cycling between room temperature and 1,000 DEG C is not more than 0.01% per one heat cycle.
