Abstract:
(EN) This gas-sensitive body is provided with a material to be supported and a metal oxide support. The material to be supported is composed of at least one substance selected from the group consisting of metals, alloys, oxides and composite oxides containing an element in groups 7-11 of the periodic table. The metal oxide support is an oxide of at least one element selected from the group consisting of Y, Ce, Ti, Zr, Nb, Fe, Zn, Al and Si. The gas-sensitive body is formed of an assembly of composite particles, each of which is obtained by having the material to be supported supported by the metal oxide support, and has electrical characteristics that change upon adsorption of a gas to be detected.
(FR) L'invention concerne un corps sensible à un gaz, qui comprend un matériau à supporter et un support d'oxyde métallique. Le matériau à supporter est composé d'au moins une substance choisie parmi le groupe constitué de métaux, d'alliages, d'oxydes et d'oxydes composites contenant un élément parmi les groupes 7-11 du tableau périodique. Le support d'oxyde métallique est un oxyde d'au moins un élément choisi parmi le groupe constitué de Y, Ce, Ti, Zr, Nb, Fe, Zn, Al et Si. Le corps sensible à un gaz est formé d'un ensemble de particules composites, dont chacune est obtenue en faisant supporter le matériau à supporter par le support d'oxyde métallique, et a des caractéristiques électriques qui changent lors de l'adsorption d'un gaz à détecter.
(JA) 本発明の感ガス体は、被担持体と、金属酸化物担体と、を備える。被担持体は、周期表の第7族~第11族に属する元素を含む金属、合金、酸化物、及び複合酸化物からなる群から選ばれる少なくとも1種でできている。金属酸化物担体は、Y、Ce、Ti、Zr、Nb、Fe、Zn、Al、及びSiからなる群から選ばれる少なくとも1つの元素の酸化物である。感ガス体は、被担持体が金属酸化物担体に担持されて形成された複合体粒子の集合体によって形成され、かつ、被検知ガスの吸着によって変化する電気的特性を有する。
