| Abstract: | Intrinsic kinetics of the hydrogen reduction of cuprous sulfide (Cu2S) have been measured. Experiments were carried out in the temperature range 823 to 1023 K using a thermogravimetric analysis
method. The reaction was studied in detail using both thin pellets and powder samples. The reaction followed first-order kinetics
with respect to the solid reactant concentration as well as the hydrogen concentration. An activation energy of 92.0 kJ/mol
(22.0 kcal/g-mole) was obtained for the reaction. Copper produced from the reaction formed filaments which sintered above
about 1000 K.
