摘要： A multilayered air-fuel ratio sensing element has a zirconic solid electrolytic body (11) and a heat-generating portion (13, 16, 22) including an alumina substrate located adjacent to the zirconic solid electrolytic body (11). The zirconic solid electrolytic body (11) is made of a partially stabilized zirconia containing 5∼7 mol% yttria and having a mixed phase structure including a cubic phase, a monoclinic phase and a tetragonal phase. The zirconic solid electrolytic body (11) has a relative density of 94∼100% with a mean sintered grain size (R ZR ) of 0.5∼3.0 µm. The alumina substrate has a relative density of 95∼100% with a mean sintered grain size (R AL ) of 0.5∼4.0 µm. And, the partially stabilized zirconia has an M/C ratio in a range from 0.05 to 0.25.

摘要： A porous honeycomb structure body, having honeycomb shaped cell walls and a large number of cells surrounded with the honeycomb shaped cell walls, and a related manufacturing method are disclosed. The cell walls have a principal composition of cordierite in a chemical composition of 45-55 % by weight of SiO 2 , 33-42 % by weight of Al 2 O 3 and 12-18 % by weight of MgO. The cell walls have fine pores formed in a distribution under which a fine pore bulk, having pore diameters of 5µm or less, is less than 15% of an entire pore bulk and a fine pore bulk, having pore diameters exceeding 25µm, is less than 10% of the entire pore bulk. The porous honeycomb structure body has porosity ranging from 40 to 60% and has a thermal expansion coefficient of 0.7 × 10 -6 /°C or less at temperatures ranging from 40 to 800°C.
