Abstract

PURPOSE: To devise remarkable improvement of sensitivity for CH4 by adding proper quantities of PtO or PdO to two-component system consists of SnO2 and ZnO.
CONSTITUTION: At least, either one of PtO or PdO of 0.01W12mol% for the total amount of SnO2 and ZnO is added to and contained in a composite consists of SnO2, 80W30%, and ZnO, 20W70% in mole percentage. The above composite is a sinter having no spinel structure and the sinter has great sensitivity both for an inflammable gas with the small number of carbon and that with the large number of carbon and will not be influenced by humidity.
