Resistivity Characterization of Ti Based ATO and its Preparation

Article Preview

Abstract:

Antimony doped tin oxide (ATO) is an oxide material with well electrical conductivity. The composite material of Ti based ATO is prepared with Ti particles (45 μm) according to the thermal decomposition method. The resistivity of the material has been analyzed with a measurement device under 1.7 MPa in particles form. The factors influencing the resistivity were studied and optimized in this work. In order to minimize the resistivity of the material, the optimum conditions are putted forward as: mass ratio of coating solution 15% (SbCl3 to SnCl4⋅5H2O), repeating coating process 20 times (coating with the solution and then dried at 100 °C), sintering at 450 °C for 15 min. Under the optimum experimental conditions, the resistivity of the composite particles is 232 Ω·m. Furthermore, ATO coating improved the properties of the composite material in the oxidation resistance.
