Title (EN) MATERIALS FOR SOLID-STATE GAS SENSORS
(FR) MATERIAUX POUR CAPTEURS DE GAZ A SEMI-CONDUCTEURS
Abstract: front page image
(EN)Solid-state compositions defined by one of the following formulae: a binary oxide of the formula Cr¿2-x?M¿x?O¿3? with M=Fe or Mn and 0.005$m(F)x$m(F)1.95; a ternary oxide of the formula Cr¿2-x?(M1¿z?M2¿1-z?)¿x?O¿3? with M1=Fe or Mn, M2=Fe, Mn or A1, 0.005$m(F)x$m(F)1.95 and 0.005$m(F)z$m(F)0.995; a ternary oxide of the formula Cr¿2-x?(M1¿z?M2¿1-z?)¿x?O¿3? with M1=Fe or Mn, M2=Ti and 0.005$m(F)x$m(F)1.95, and 0.005$m(F)z$m(F)0.45; a quaternary or quinternary oxides of the formula Cr¿2-x?((M1¿a?M2¿b?M3¿c?)¿z?M4¿1-z?)¿x?O¿3? with M1=Fe, M2=Mn, M3=A1 and M4=Ti, and O$m(F)a,b,c$m(F)1, 0.005$m(F)x$m(F)1.95, and 0.005$m(F)z$m(F)0.45; and their use as gas sensors.
(FR)L'invention concerne des compositions à semi-conducteurs définies par un oxyde binaire représenté par la formule Cr¿2-x?M¿x?O¿3? où M=Fe ou Mn et 0,005$m(F)x$m(F)1,95; un oxyde ternaire représenté par la formule Cr¿2-x?(M1¿z?M2¿1-z?)¿x?O¿3? où M1=Fe ou Mn, M2=Fe, Mn ou A1, 0,005$m(F)x$m(F)1,95 et 0,005$m(F)z$m(F)0,995; un oxyde ternaire représenté par la formule Cr¿2-x?(M1¿z?M2¿1-z?)¿x?O¿3? où M1=Fe ou Mn, M2=Ti et 0,005$m(F)x$m(F)1,95, et 0,005$m(F)z$m(F)0,45; et un oxyde quaternaire ou quinternaire représenté par la formule Cr¿2-x?((M1¿a?M2¿b?M3¿c?)¿z?M4¿1-z?)¿x?O¿3? où M1=Fe, M2=Mn, M3=A1 et M4=Ti, et O$m(F)a,b,c$m(F)1, 0,005$m(F)x$m(F)1,95, et 0,005$m(F)z$m(F)0,45. L'invention concerne également l'utilisation de ces capteurs de gaz.
