摘要：

Bulk gas sensors composed of various atomic ratios of ZnO and SnO2 were fabricated and their gas sensing characteristics were investigated, After powder mixtures of ZnO and SnO2 together with equal weights of camphor were pressed into disks, they were sintered at 1200 degrees C for 3 h in air. The relationship between the atomic ratio of ZnO and SnO2 and the gas sensing characteristics was investigated, As a result of the measurements of the conductance of these gas sensors upon exposure to 2vol% i-C4H10 gas, the sensor consisting of Zn : Sn = 0.68 : 0.32 was found to have the highest sensitivity. After the atmosphere was changed from i-C4H10 to air, the conductance returned to almost the initial level within 1 min.
