Electrical properties of high-temperature conducting powder MoSi2-SiC-Y2O3 materials

Conclusions We examined the concentration and temperature dependences of the specific electrical resistivity in the two- (MoSi₂-SiC) and three-phase (MoSi₂-SiC-Y₂O₃) systems in the temperature range 100–1800°C. In the two-phase system, the lowest TCR in heating to 1800°C was recorded for the materials with the mass content of SiC of 20–40%. The results show that the TCR of the two-phase materials of the MoSi₂-SiC system can be reduced by adding yttrium oxide to them.Translated from Poroshkovaya Metallurgiya, No. 6(306), pp. 83–85, June, 1988.
