Abstract

Abstract: The effects of sintering temperature and film thickness on the gas-sensing properties of SnO₂ thick film sensors were researched by measuring the ethanol gas sensitivity of the samples with different thickness films prepared by screen printing technology and sintered at different temperatures. The results show that different thickness films and different sintering temperatures greatly effect the gas-sensing properties of the samples.

Key words: SnO₂ gas sensors, film thickness, sintering temperatures, gas-sensing properties
