Title:
タングステン系化合物及び硫化水素検出器用電極の被覆方法
Document Type and Number:
Japanese Patent JP3556687
Kind Code:
B2
Abstract:
Tungsten carboxylate compounds (Formulas I, II, and III) useful for coating interdigitated electrodes (17,17') used in hydrogen sulfide gas sensors (22) are disclosed. A method of coating electrodes with the compounds using a precise solution casting technique such as spin-coating or casting, dip-casting or spray-casting techniques is also described. Electrodes (17,17') which are solution coated with the compounds may be used to fabricate superior quality chemiresistor sensors (22) for use in hydrogen sulfide gas sensing devices by heating the carboxylates above 350 DEG C to decompose certain carboxylates to WO3 and others to sodium tungstate.
