AbstractThe solid state sintered SiC (SSiC) ceramics are mainly used for structural materials, but they are rarely used for electronic devices and resistance components. In this work, the electrical properties of the SSiC ceramics with different carbon additives were investigated, including V-I characteristic, the relationship between current and resistance, as well as the relationship between temperature and resistance. These results show that the SSiC ceramics present obvious nonlinear electrical behavior and their resistance decreases with the current increase. When the electrical field intensity is over 15.8 V/mm for the SSiC ceramics with 3wt% carbon additives, as well as 70.7 V/mm for the SSiC ceramics with 6wt% carbon additives, the boundary barrier is breakdown and the resistance becomes very low, due to the resistance being only controlled by the grain size. The resistance of the SSiC ceramics decreases with the temperature increase at the electrical field intensity of 1 V/mm, indicating thermo-sensitive characteristic of SSiC ceramics of which the resistance is changed from 106Ω·cm at 25 to 5 Ω·cm at 400. © 2017, Science Press.
