摘要： A catalytic material for removing nitrogen oxides comprises a complex oxide as main phase. The complex oxide has a spinel structure and contains metallic elements of Al, Ga, and Zn. The mole fraction x (%) of Zn on oxide basis is greater than 0 and less than 50. Nitrogen-oxides-containing gas and a reductant such as methane or propylene are brought into contact with the catalytic material so as to remove, through reduction, nitrogen oxides from the nitrogen-oxides-containing gas. The catalytic material can be used to remove nitrogen oxides contained in exhaust gas from an automobile or the like. The catalytic material can remove nitrogen oxides even in exhaust gas of a high oxygen concentration and requires no toxic reductant such as ammonia.

摘要： A temperature sensor element 10 has a reduced thermal conduction path from a measurement object to a sensitive end portion 22 of a thermocouple 21 and a high-dense insulating ceramic base body 20. Since the temperature sensor element 10 has excellent thermal conductivity from the measurement object to the sensitive end portion 22 of the thermocouple 21, it is also excellent in responsiveness at the time of temperature detection. Further, corrosion and material deterioration of the thermocouple 21 is unlikely to occur because the thermocouple 21 does not directly contact the measurement object (exhaust gas). As a result, the temperature sensor element 10 exhibits excellent durability. Therefore, the temperature sensor element 10 exhibits a good responsiveness at the time of temperature detection as well as excellent durability.
