补充资料:气敏效应
分子式:
CAS号:

性质:又称嗅敏效应。某些半导材料表面吸附(有物理吸附,化学吸附或和物理化学吸附)某种气体引起表面能态发生改变,从而导致材料电导率变化的现象。利用此效应可制成气敏电阻器。通常可分为电导式和电化式两类。前者是利用气体吸附导致感知母体导电率发生变化,后者是利用固体电解质离子选择渗透性。气敏电阻器材料主要有二氧化锡,氧化铁系,五氧化二钒系、二氧化锆系,氧化镍系,氧化钴系及稀土过渡金属氧化物系,如Ln(Ni,Co)O3等。气敏电阻器具有灵敏度高、工作温度低、结构简单、使用安全和成本低等优点。可用于氢、乙醇、一氧化碳,城市煤气,石油液化气,氟里昂气,钢水中氧气检测等许多场合。对于各种管道和密封系统的探漏、环境污染监测,安全防火和自动控制等也有广泛应用。
