Operating Range

The possibility of developing electric heaters based on cerium dioxide for air with an operating range of 300‒2500 K is discussed. The influence of various factors on the electrical conductivity of CeO2 ceramics has been investigated. The main physicochemical and ceramic properties of ceramics are characterized. Ill. 2. Ref. 8.

The influence of Mn addition (from 1 up to 10 mol%) on densification and electrical conductivity of CeO2 was studied in detail. Bulk specimens were prepared by the conventional technique of mixing suitable amounts of cerium dioxide and manganese carbonate, followed by pressing and sintering. The apparent density of sintered specimens was determined by the immersion method and electrical characterization was carried out by impedance spectroscopy measurements in the 300 to 550 °C range. High densification (> 95% of the theoretical density) was obtained for small addition of Mn (1 mol%) to CeO2 sintered at 1300 °C for only 0.1 h. Electrical conductivity changes in sintered pellets depend on the sintering procedure, but not on the manganese content.
