Research and Development of Nanometer Al2O3 Material Made for Rapid Detection of Gas Concentration Sensor

Abstract:

Coal Face Gas Concentration Overrun Is the Leading Cause of China Coal Mine Fatal Gas Explosion Accidents Reasons. Therefore, Research and Development of Rapid Detection of Gas Sensor Can Avoid Gas Explosion Accident Key. this Paper Studies the Al2o3 Nanometer Powder Preparation Technology, by Doping Rare Earth Material so that the Gas Sensor Detection Element Surface Area Was Greatly Improved; its Sensitivity and Stability Are Greatly Improved. According to the Test Results Show that, the Rapid Gas Sensor for Methane Reaction Time Is 6 Seconds, Recovery Time of 8 Seconds.
