Abstract
It is an object of the present invention to provide a ceramic member with excellent balance between oxygen ion conductivity and endurance (resistance to cracking and the like), an oxygen ion permeation module and a chemical reactor such as an oxygen separator, using such a ceramic member. The ceramic member with oxygen ion conductivity in accordance with the present invention has a perovskite-type crystal structure and a composition represented by the general formula:()()(where Ln represents at least one element selected from lanthanoids, and M represents at least one element selected from the group containing Sr, Ca, and Ba, 0<x<1, 0.4≦y<1, x+y≧1). The oxygen ion permeation module composed by employing such a ceramic member can be used as a structural component of an oxygen separator, an oxidation reactor (for example, a reactor for partial oxidation of hydrocarbons), and the like.
