Abstract
PURPOSE: To increase the strength of the element and enhance the stability with lapse of time of the gas sensitive characteristic by forming the detection element material, impregnating the burnt member with the sinter prevention agent solution and burning further more.
CONSTITUTION: The element material containing N-type metal oxide such as SnO2, FeO3 is made, for example, in a powder, and formed to a desired shape, and this formed or molded member is burnt to make the sintered member. Then, the thus obtained burnt member, for example, is oxidized to impregnate the metal salt to be oxide such as SiO2, NiO, PbO with the solution of the sintering prevention agent dissolved in the solvent such as water, alcohol to obtain the sintered member impregnated with the sintering prevention agent solution. Then the sintered member is dried and further burnt at the temperature higher than the temperature that the metallic salt in the impregnating metallic salt solution is decomposed to oxide. Thus, the element can be obtained in which the element strength is large and the good gas sensitive characteristic with stability with the lapse of time.
