Abstract

Synthesizing of indium oxide (In2O3) nano particles using sol-gel process as an active sensing material of gas sensor has been carried out. As starting material, indium acetate/In(CH3COO)3 was dissolved in diethylene glycol and heated up at 1300C until homogeneity is achieved. Nitric acid (HNO3) was added under vigorous stirring where the resulting mixture was heated at 1800C for 5 hours. After drying at 4000C for 2 hours and annealing at 5000C for 1 hour, a yellow fine powder was obtained, which was identified by using XRD and SEM. From the observation it has been found that the materials are in nano size range.
