The oxidized form of a model, fused iron catalyst for ammonia synthesis, containing large amounts of wustite (ca. 40 wt.-%), was activated by reduction. The reduction of catalyst samples with different thermal history and different grain size was continuously monitored by thermogravimetry as well as
