Stoichiometric and nonstoichiometric powders of cadmium indium oxide were derived from calcination of cadmium indium sulphide prepared by flux method. The materials were confirmed by XRD. Thick films of above prepared powders were prepared on glass substrates using screen printing technique. The thick films were characterized by SEM and EDAX. The electrical conductivity of CdIn 2 O 4 thick films was calculated. The gas sensing performance of stoichiometric thick films of CdIn 2 O 4 was tested for various gases. The films showed good response to LPG.
