Chromium resistivity

WebMay 24, 1985 · Abstract. The electrical conductivity and thermal stability of sputtered chromium oxide films were investigated in order to assess their potential as protective coatings for high temperature battery electrode materials. Sheet conductivities as high as 10–15 Ω -1 cm -1 were achieved in air at a temperature of 350 °C. WebJul 1, 2024 · Since the chromium ions do not contribute to the conduction process due to its stable valence state [27], the number of electrons hopping between Fe2+ and Fe3+ decreases, leading to an enhanced resistivity. However, abnormal decrease of electrical resistivity at x=0.2 and 0.3 is observed.
