摘要：

Nanosized SnO2 powder was synthesized by thermal decomposition of tin di acetate at 380 degrees C. The effect of permanent binder (5, 10, 15, and 20 wt%) on the electrical and gas-sensing properties of thick film planar resistors shows sheet resistivity four to five orders of magnitude smaller, with comparatively low temperature coefficient of resistance. The sensors with 15 wt% of glass show the highest sensitivity toward H-2, CO, and liquefied petroleum gas (300 ppm) at optimal temperatures of 150 degrees, 220 degrees, and 190 degrees C, respectively, giving selectivity. The sensors are tested for 10-300 ppm of gas with a response and recovery time of 10 and 20 s, respectively.
