Abstract

Oxides characterized as ionic conductors have experienced increased scrutiny in recent years in the interest of ceramic sensor technology. Applications of such devices abound in the areas of materials research, process metallurgy, and physiological measurements.

This investigation in concerned with the measurement of the oxygen partial pressures In gases using commercially prepared zirconia tubes partially stabilized by an addition of calcla as the electrolyte In a high temperature, solidstate, electrochemical gauge. This material was chosen because of improved thermal shock resistance over fully stabilized zirconia. The flow sensitivity of the gauge to various gases is discussed and the results of using the gauge as an oxygen analyzer are reported. A method of blending gases In order to obtain a range of quantifiable oxygen partial pressures for use in materials research is also Included.
