ABSTRACT:
A sintered body of a ceramics material consisting essentially of a mixture of lanthanum chromite of the formula of LaCrO.sub.3 with an oxide of a specifically limited metal, or consisting essentially of lanthanum chromite, whose Cr is partly replaced by a specifically limited metal, has high mechanical strength and electroconductivity and is very useful as an interconnecting member of fuel cell. A mixture of lanthanum chromite, whose Cr is partly replaced by a specifically limited metal, with an oxide of a specifically limited metal is effective for obtaining a sintered body having high mechanical strength and electroconductivity in a high sinterability.
