摘要: In a high temperature gas measuring device consisting of zirconia oxide solid electrolyte cell bonded to support member, sealant exhibiting thermal coefficient expansion comparable and melting point in excess 1000° C. is used seal the member. The preferred sealants which meet these requirements include: (1) 3 MgO.sup.. Al 2 O .sup.. 6 SiO (2) 52% Nd 4 (SiO ) , 48% Ca (3) 57% La 43% (4) 50% Y (5) (a) : 50 mol % each (b) 40% 60% .
