Nano Fe2O3 Powder in Sensitive Materials1.Ultrafine Fe2O3 has semiconductor property, and its conductivity is sensitive to the temperature, humidity and gas, thus it is a potential sensitive materials.2.Gas sensor, using of metal oxides with the surrounding atmosphere of the gas composition changes, electrical properties (such as resistance) to change the gas to detect and quantify the gas. The particle size used for the gas sensor is one to several microns. The smaller the particle size is, the larger the specific surface area is. The greater the interaction between the surface and the surrounding contact surface, the higher the sensitivity.3.After experiment, it was found that α-Fe2O3 ultrafine powder has a good sensitivity.4.Fe2O3 prepared by precipitation method made of gas sensors, the detection found that pure α-Fe2O3 conductivity is very small, the mass fraction of 0.5% CO less sensitive. By incorporating appropriate noble metals and carbonates and oxides, the conductivity and sensitivity can be significantly increased.
