摘要
氧气传感器被普遍应用于废气控制、钢铁生产、气体检漏等工业过程中。寻找成本低、灵敏度高的氧气传感材料是一项有意义的工作。本文报告某些铋铌氧化物固溶体材料的热电势对氧压的关系,探讨这种原理的应用前景及需要解决的问题。 均相材料Bi_(60)NbO_(92.5)和Bi_(31)NbO_(49)由Bi_2O_3和Nb_2O_5固固反应获得。制备方法参见文献[1]。将粉末产品压成直径13mm,厚度3mm的圆片,在1100K烧结24小时。
Thermoelectric power of Nb_2O_5 doped β-Bi_2O_3 solid sclutions has been measured inair, pure O_2, 0.1%NO/O_2 and found to have high sensitivity to oxygen partial pressure.The possibility of developing a new type oxygen sensor based on the measurement of ther-moelectric power has been discussed.
