Abstract: In this paper, we explore for the first time the compositional, morphological and structural properties of the ZrO2 thick films prepared by standard screen printing method and fired between 800 oC to 1000 oC for 2-hours in an air atmosphere. The material characterization was done by using XRD, X-ray energy dispersive analysis (EDAX), and scanning electron microscope (SEM). The deposited films were polycrystalline in nature. Also samples were found uniform and adherent to the alumina substrate. Effect of firing temperature on structural parameters such as grain size and surface area were calculated. The result indicates that grain growth can be increased by increasing firing temperature which is responsible for decreasing surface area. From the EDAX analysis it was found that the ZrO2 films are non- stoichiometric in nature which is due to semiconducting behavior of the films.
