Abstract
PURPOSE: To enhance the performance by adding chromium oxide to indium oxide.
CONSTITUTION: A main composition of effective compositions showing a gas detecting ability is composed by indium oxide and subcomposition is composed by at lease one of chromium oxide and hafnium oxide. When considering all indium oxide as In2O3 all chromium oxide as Cr2O3, all hafnium oxide as HfO2, respectively, at least one ratio of chromium oxide and hafnium oxide occupying in the effective compositions is set to be 5W50wt%. Thus, by specifying the type and wt% of the subcomposition, without diminishing the excellent gas sensing characteristic of indium oxide, the element resistance value can be enhanced to a practical field.
