Abstract

At least one leg, preferably the positive leg, of a thermocouple contains a thermoelectric alloy of the composition:- .(Mo1-yMy)(Si1-xAlx)2 .where M=one or more of Ti, Zr, Hf, Nb, .Ta, V, W, Cr .x=0,2-0,6 .y=0-0,5 The negative leg preferably contains Mo Si2 and both legs are made by sintering powder of the appropriate material admixed with up to 30% by weight of a ceramic binding agent e.g. silica. The above combination may also act primarily as a heating resistor and be used as a thermocouple only for short periods to obtain a voltage for controlling the current input to the resistor through a relay. Specifications 731,616 and 739,693 are referred to.
