Synthesis and Characterization of Zirconia (ZrO2) by simple Sol-Gel Route

Abstract: It is well known that sol-gel technique is a simple and cost effective method to produce ceramic powders. The present study deals with the synthesis and characterization of ZrO2 nanopowders. Since ZrO2 possesses diverse electronic and optical properties, it is potentially utilized in the applications of gas sensors, solid fuel cells, high durability coating, catalytic agents, etc. Based on sol-gel technique, the synthesis of ZrO2 is carried out using Zirconium alkoxide as the starting material followed by drying the gel and heat treated at 700 oC for 1 hour. Structural characterization and crystalinity were studied using X-ray diffraction. Microstructural and morphological characterization was performed using electron-microscopic technique - scanning electron microscopy (SEM).
