Abstract

PURPOSE: To quicken response, by sharpening a shape of the distribution of the grain size of powder, which consists of a transition metal oxide manufactured by means of a normal ceramic technique, by classification operation.
CONSTITUTION: An oxygen concentration detecting element is produced by transition metal oxide powder, which has a grain size component not less than 90wt% within a grain size range of 0.3W15μ and is classified so that the ratio B/A of grain size B, in which an integrating residual component becomes to 30%, to grain size A, in which the integrating residual component becomes to 70%, become not more than 1.35 when a cumulative frequency distribution curve of the powder is indicated in the weight % of the integrating residual component. Titanium dioxide can be used as the transition metal oxide, for example.
