Bulk gas sensors composed of various atomic ratios of ZnO and SnO_2 were fabricated and their gas sensing characteristics were investigated. After powder mixtures of ZnO and Sn0_2 together with equal weights of camphor were pressed into disks, they were sintered at 1200℃for 3h in air. The relationship between the atomic ratio of ZnO and Sn0_2 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-C_4H_ 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-C_4H_ to air, the conductance returned to almost the initial level within I min., rights: 社団法人日本セラミックス協会rights: 本文データは学協会の許諾に基づきCiNiiから複製したものであるrelation: isVersionOf: http://ci.nii.ac.jp/naid/110002291423/
