Paper Title:
Effect of V2O5 Additive on the Microstructure and Electrical Properties of Mn-Co-NiO NTC Thermistor
  Abstract

The aim of this paper is to investigate the effects of V2O5 additive on the electrical properties of NTC thermistors based on Ni0.5Co0.5Mn2O4.The XRD analyses indicate that single spinel phase can form, and V2+ions are in the octahedral interspace. The cell can be enlarged due to the V2O5 additive. The resistivities (ρ) and the material constant (B) increase obviously, the reasons of which are mainly attributed to the outer electron configuration of V2+ and cell enlargement.
