“…For the advantage of ceramics on the thermal and chemical stability, some conductive ceramics, including silicon carbide, titanium dioxide, boron carbide and carbon, are considered as candidate materials for thermocouples [3,4,5]. But the results of previous research show that such thermocouples have some certain disadvantages [6,7]. Such as, thermocouples employing carbon are limited to work below 500 ºC in an oxidation environment owing to oxidation of carbon.…”
