ABSTRACT:
A cation emission type halogenated hydrocarbon gas detecting element comprising a cation source, a heating means and an ion collector electrode, which is characterized in that said cation source consist essentially of .beta.-Al.sub.2 O.sub.3, wherein substantially all cation species occupy a position in the crystal lattice structure of the source. By employing .beta.-Al.sub.2 O.sub.3, the detecting element can be more miniaturized and can work at lower temperature than a conventional cation emission type electrode comprising the cation source made of steatite.
