where d = thickness of the film, ,o = resistivity of the film, = resistivity of the bulk material having the same structure and approximately the same number of defects as the films, l0 = mean free path of the charge carriers. The values of l0 calculated by the two methods were found to agree satisfactorily. Figs. 7 and 8 show the variation of the Hall mobility (/̂ H) with film thickness and sub...

SOLID STATE REDUCTION OF CHROMITE IN HIGH CARBON FERROCHROMIUM-CHROMITE COMPOSITE PELLETS

Abstract: In this paper solid state reduction of high carbon ferrochromium-chromite composite pellets in the temperature range of 900-1350°C was investigated. A two stage reduction mechanism is proposed. The first stage is likely to be controlled by the chemical reaction with activation energy of 127.2kJ/mol. In the second stage, solid state diffusion of carbon through the reaction product ...
