In this study, the features of the SnO2 gas sensor were examined and the effects of metal oxide semiconducting requisites such as La2O3 and Fe2O3 on the gas sensor system were searched. Sensor fabrications were carried out with thick film sensor design. Inorder to obtain these thick film sensors, a mixture called binder was transferred from nano-sized masks to alumina surfaces by screen printing technique. The name of this mixture is binder. Binder mixture consists of ethyl cellulose, alpha terpineol, active powder mixture. However, in order to obtain a quality sensor, it is necessary to pay attention to the proportion of this mixture, the mixing times and temperatures. A binder was prepared by adding 30% active powder to the paste solution taken in the ratio of 70% by weight. Ethyl cellulose was mixed with alpha terpineol at 40 °C for 3 hours at 150 rpm at 1:10.
