Abstract
The research about synthesis and fabrication of thick film Fe2O3-ZnO had been done to identify the electrical properties of thick film. The synthesis of thick film material was done by using precipitation method. Then, the fabrication was done by using screen printing method. The thick film was fired at 800°C for 2 hours. By electrical properties testing, it is informed that the increased temperature is accompanied by decreased resistance of the sample. The ethanol gas concentration also affects the resistance of the sample. Besides, the sensor gives a response of 100 ppm ethanol at the working temperature in the range of 180°C-320°C. Meanwhile, it also gives a response of 300 ppm ethanol at working temperature in the range of 180 °C-400°C. Based on the data, the response increases with the ethanol concentration addition. Thus, the sensitivity of thick film is inflicted by the increasing of ethanol concentration. Considering to the simple synthesis by using precipitation method and gas-sensing electrical properties, the thick film would be a promising candidate for applications in ethanol gas sensor.
