A composite solid electrolyte material for use in oxygen sensors, which comprises a mixture of at least two ceramic constituents, one of which is a good oxygen ion conductor and the other a non-electrolyte, is useful for oxygen sensor fabrication. Particularly, it enables gas analysis oxygen sensors to be produced by conventional techniques because the coefficient of thermal expansion of the composite electrolyte material can be closely matched to the material of a supporting sensor body. The closeness of thermal expansion coefficients means that oxygen sensors can now be formed in the 'green' state, then fired.
