通过主体材料 Sn O2 掺入多种掺杂剂对气敏特性影响的研究 ,得到了对氨气 ( NH3)敏感的材料的较佳配方 ,该敏感材料制作成的气敏传感器对氨气具有较高的灵敏度和较好的稳定性。
Through the study of the effect of SnO2 doping on the gas-sensing properties, the best formula of the NH3-sensitive material was obtained. The gas sensor made of the sensitive material has a better performance on ammonia High sensitivity and good stability.
