Oxygen ion conducting ceramic materials are disclosed, represented by the formulas ##EQU##Ni(Nb 1-x M x ) 2 O 6-x and Ni 2 (Nb 1-x M x ) 2 O 7-x, wherein M is selected from the group consisting of Zr +4, Ti +4, Sn +4, Sm +4, Hf +4 and Ce +4 and x is a value from 0 to 0.2. These materials, along wit
Oxygen ion conducting ceramic materials are disclosed, represented by the formulas ##EQU##Ni(Nb 1-x M x ) 2 O 6-x and Ni 2 (Nb 1-x M x ) 2 O 7-x, wherein M is selected from the group consisting of Zr +4, Ti +4, Sn +4, Sm +4, Hf +4 and Ce +4 and x is a value from 0 to 0.2. These materials, along with Bi 2 O 3 in solid solution with Y 2 O 3 or Nb 2 O 5, may be used in an oxygen separator for removing oxygen from a first gas to a second gas or vacuum. The oxygen separator includes at least one layer of the ceramic material with layers of a porous metallic conductor arranged on either side to form a body. An electrode connects one layer, and a second electrode connects the opposite metallic layer. A voltage signal is applied across the electrodes, whereupon oxygen ions diffuse through the ceramic layer.
