Abstract
To develop high-temperature heat elements with a small temperature-coefficient electrical conductivity, small-grained MoSi2-SiC ceramics were prepared by reaction sintering ceramic precursor with molybdenum powder. By second sintering at 1773 K for 10 h, two phases of MoSi2 and β-SiC were formed. The average grain size of both MoSi2 and SiC ranges several tens nanometers. Electrical conductivity measurement revealed that conductive behavior changed from semiconductive to metallic with increasing molybdenum disilicide content. 54.3 wt% MoSi2/β-SiC composite showed an almost constant temperature coefficent in the temperature range at around to 600-850 K.
