摘要：

Reference systems for potentiometric oxygen sensor in molten 44.5% lead - 55.5% bismuth alloy have been evaluated. Two types of reference systems have been considered: metal / metal oxide and gas with a defined oxygen partial pressure. In/In2O3 and Sn/SnO have been chosen as a metal / metal oxide reference system, and Pt/air is the gas reference system tested. The sensor performance using all three reference systems has been Ar + 10% K or 99.999% Ar) and air (20% O-2). All the tests have been performed in stagnant conditions at 500 degrees C in an autoclave.
