Paper Title:
The Resistivity-Temperature Property of Transition Metal Oxide Co3O4 with In2O3 Addition
  Abstract

The electrical and structural properties of the mixture of Co3O4 and In2O3 were studied. All the samples were added with 2% nanocrystalline SiO2 and sintered at 1000°C for 2 hours. The sintered bodies of the samples were of high density and the average particle size was ~2μm. The materials showed the NTC behavior in a wide temperature range (100-350°C). The resistivity of the materials at room temperature decreased with increase the content of the In2O3 from 0% to 10%. The thermistor constant (B) values and activation energy(E) were 7835, 6637, 5903K, and 0.675, 0.572, and 0.509 eV as the content of In2O3 were 0%, 5% and 10%, respectively.
