Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.
